C++ vs Ruby: What are the differences?
Key Differences between C++ and Ruby
Memory Management: One of the major differences between C++ and Ruby lies in their memory management approach. In C++, developers have to manually manage memory using concepts like new and delete, which can lead to memory leaks and other low-level errors. On the other hand, Ruby uses automatic garbage collection, where the memory is managed by the interpreter itself, relieving developers from the burden of memory management.
Type System: C++ has a static type system, which means that variables must be declared with their types, and these types are checked at compile-time. This provides better performance and allows for more efficient memory usage. Conversely, Ruby has a dynamic type system, allowing variables to be assigned to different types at runtime. While this provides flexibility, it can also make debugging more challenging.
Syntax and Readability: C++ tends to have a more complex syntax compared to Ruby, which is known for its simplicity and elegance. C++ often requires more boilerplate code and explicit syntax for tasks like string manipulation or file I/O. Conversely, Ruby focuses on readability, utilizing a more concise and human-friendly syntax, which makes it easier to understand and write code quickly.
Concurrency and Parallelism: C++ has better support for low-level concurrency and parallelism, as it allows for direct access to threads and low-level synchronization mechanisms like mutexes and condition variables. In contrast, Ruby has limited built-in support for concurrency and parallelism due to its interpreter-based nature. However, Ruby provides abstractions like fibers and the ability to leverage external libraries to achieve concurrency.
Performance: C++ is often considered a faster language than Ruby due to its direct compilation to machine code and static typing. C++ programs can be highly optimized and offer better performance in scenarios where speed is critical, such as system programming or performance-sensitive applications. Ruby, being an interpreted language, often has a performance overhead and is better suited for rapid prototyping and web development.
Community and Ecosystem: C++ has a long-established and robust community with a wide range of libraries, frameworks, and tools available. It is widely used in industries like gaming, embedded systems, and high-performance computing. Ruby, on the other hand, has a smaller community but is known for its supportive and passionate community. It shines in web development and has a rich ecosystem with powerful frameworks like Ruby on Rails.
In summary, C++ provides more control over memory management, has a static type system, and offers better low-level performance, while Ruby focuses on simplicity, readability, and rapid development. Both languages have their strengths and are suited for different use cases based on the specific needs of a project.
Hello!
I'm a developer for over 9 years, and most of this time I've been working with C# and it is paying my bills until nowadays. But I'm seeking to learn other languages and expand the possibilities for the next years.
Now the question... I know Ruby is far from dead but is it still worth investing time in learning it? Or would be better to take Python, Golang, or even Rust? Or maybe another language.
Thanks in advance.
Hi Caue, I don't think any language is dead in 2022, and we still see a lot of Cobol and Fortran out there, so Ruby is not going to die for sure. However, based on the market, you'll be better off learning Goland and Python. For example, for data science, machine learning, and similar areas, Python is the default language while backend API, services, and other general purpose Goland is becoming the preferred.
I hope this helps.
I feel most productive using go. It has all the features I need and doesn't throw road blocks in your way as you learn. Rust is the most difficult to learn as borrow checking and other features can puzzle a newcomer for days. Python is a logical next step as it has a huge following, many great libraries, and one can find a gig using python in a heartbeat. Ruby isn't awful, it's just not that popular as the others.
Another reason to use python is that it is not compiled. You can muck around in the interpreter until you figure things out. OTOH, that makes it less performant. You really need to think about your use cases, your interest in lower-lever versus high-level coding, and so on.
I enjoy coding in Python. I think it's minimalistic and readable syntax and lang features are just unparalleled. They are perfect for prototyping and for the software engineering in general. If I'm not wrong Gitlab marked Python as #2 popular language after JavaScript. Beyond that, Python ecosystem and areas of usage are enormous. In areas like ML/DL, it's important to know Python to leverage variety of existing tools and frameworks.
Then, I have learned and worked with Golang. I use it where I think I would need a slightly better performance than in Python. Plus, relatively small and self-contained executable is a great thing to have. If you plan to write distributed systems, extend Kubernetes or do similar things I think Golang is a great choice. It's also simple and straightforward, especially when you want to do effective multithreading. Although I don't like that Golang is more low-level than Python. Sometimes I feel like I need to implement myself too much things.
Now, about Rust. It's my second try to learn Rust. First time I decided to learn Golang as I understood it in 30mins or so while I was struggling to compile/do anything meaningful there for quite a bit. So I personally don't think Rust is super easy. I have got back to learning Rust as it's going to fill one of gaps in my problem solving toolkit - let me write low-level system programs (e.g. linux kernel modules). I don't want to learn "obsolete" C/C++ (my reasons are similar to why Google has recently introduced Carbon - a replacement for C/C++ codebases). If you are not going to tight your life with system-like programming, Rust may be an overkill for you.
Finally, I have never coded in Ruby, so are not going to comment it.
Since you are very experienced, picking up a language will not take you more than a week. Rust is a very new language. Many startups are still experimenting with it. Golang is very popular nowadays. You can see a lot of golang jobs in the market. The best part is, compiled code is single binary and has a minimal footprint. Rails is a compelling framework; believe me, many websites like Shopify, GitHub, GitLab, etc., are powered by the rails framework. You can also leverage the power of metaprogramming in Ruby. Python is memory and CPU intensive. It is not as performant as the other three. If you want to go into Data Science, Python is the language. Good luck, buddy. Feel free to connect with me: https://twitter.com/avirajkhare00
Because it opens endless possibilities you can do anything and everything you want to. from ai to app development to web development.
I'm almost same position as you. 8 years same company with c#. I tried both Python and Golang. I like working with Golang. Check this litte go doc. After reading this document and following its examples, I decided to work with "go" https://www.openmymind.net/assets/go/go.pdf
Either Python or Golang, for all the enlightened reasons already mentionned in all advices/comments :) Enjoy!
I will use Elixir for personal projects. It's productive, reliable, secure, simple, etc. But when performance is critical, I need job opportunities, when I work with mutability, which do I pick? I need advice on which "bureaucratic, mainstream" programming language to pick when wanting performance and jobs. Elixir is often "slow", and it hasn't boomed yet the way Golang and Rust have, so which?
Well for those performant tasks maybe you can use Rust nifs for elixir. Elixir enables to write fault-tolerant, scalable code for concurrent systems, and as such, it is perfect for messaging systems and web applications that might need to handle a lot of users efficiently. But if you need speed you can plug in Rust or write a microservice using Goland/Rust.
include include int main(){ char name[10], pasword[10]; printf("enter you user name :"); gets(name); printf("enter your pasword : "); gets(pasword); printf("your name : %s \n your password : %s \n", name, pasword); if ( name != "youcef") { printf("name undefined\n"); } else { printf("finde name"); }
}
his not working
You will want to do a few things here. First, replace gets
with fgets
. Then, you're going to want to use strcmp
from string.h to compare the input with the desired result. The code listed below has been updated with a working example with the previously mentioned recommendations. This isn't perfect and there are other ways to accomplish the same task. Explore other options that are available when you have a chance and see if you can improve on this example.
#include <stdio.h>
#include <string.h>
int main()
{
char name[10],
pasword[10];
printf("enter you user name :");
// Use fgets as gets is insecure and can easily lead to buffer overflow exploits
fgets(name, sizeof(char) * sizeof(name), stdin);
// Remove \n from fgets stdin read with null character so as to not have to include
// in strcmp later.
name[strlen(name) - 1] = '\0';
printf("enter your pasword : ");
fgets(pasword, sizeof(char) * sizeof(pasword), stdin);
printf("your name : %s \n your password : %s \n", name, pasword);
// If strcmp result > 0 || < 0 it's not a match
if (strcmp(name, "youcef") != 0)
{
printf("name undefined\n");
}
else
{
printf("finde name");
}
}
Dear, Yusuf You can't use if statement to compare two strings, but you can use strcmp() function which means string compare The behavior of strcmp function is: If (string1 < string2)? Then: return a negative value. If (string1 > string2)? Then: return a positive value.
If(string1 == string2)? Then: return (0).So, you can modify this statment to: if(strcmp(name,"Yousef") != 0) printf("name undefined\n");
else printf("find name");But, In this case there is one logic problem that (strcmp) function don't ignore the letter case. For example: If you input name : yousef
The first letter here (y) is small, but in the comparing statement above is capital, So the result will be "name undefined", but in fact "yousef" = "Yousef".To solve this problem you should use stracasecmp() function. This function ignore the letter case while comparing. The code will be: if(strcasecmp(name,"Yousef") != 0) printf("name undefined\n");
else printf("find name");Attention: Include string libreary after using these functions to skip any problem may be found.
includemay Allah bless you ^_^
Hello, I am interested in learning how to program. I am a beginner, and many articles saying I should go with Python if I am new to programming. I considered Lua a long time ago, but for my career, I believe major programming languages should be better for me. I'm considering Python at this moment, but if you have other tools I should use, let me know.
Although Lua is a very simple,efficient, elegant and welcoming language, Python is extremely versatile. Therefore, if you want to get into programming without a defined direction, Python is the way to go. It has a lot of libraries, the ability to do anything and it is closer to other languages than Lua is (yeah I know about Lua and C, but from a learner's point of view, it makes sense). Additionally, Python will be a marketable skill, but I for one have not yet seen job offers for Lua devs.
The language you choose is also dependant on the type of career / area of programming you wish to focus on: Web Based and mobile applicaitons I would lean towards Java, PC Applications I tend to like C#, Embedded industry C, C++
my advice , you should answer me for this question, what do you like to work: web base or mobile native or cross platform. if you like web base you should choose PHP or ASP.net or Node.js or if you like mobile native you should decide Android or IOS platform and else if you like cross platfrom you should learn Flutter with dart language. thanks
Hi, I'm just starting to learn code, and I stumbled upon this website. I think I should learn JavaScript, Python, and C++ to begin with. I'm a quick learner so I am only worried about what would be more useful. Suppose my goal is to build an online clothing store or something. Then what languages would be best? I need advice. Please help me out. I'm 13 and just beginning and it's hard to understand when people use technical terms so please keep it simple. Thanks a lot.
Go with Python. It's syntax is really simple and less verbose compare to others. You can use Python for basically anything like web dev, task automation, data science, data engineering, cybersecurity etc. At initial level, it's more important to get an understanding of programming fundamentals. Once you get conformable with coding in general, then you can explore other languages.
I would worry less about languages when you're first starting out. If you want to build an online store, then javascript is a great language that is used all over the web! Get comfortable with your first language, learn some computer science concepts and how to build things the right way, and then just work towards a goal and learn as you go!
https://www.w3schools.com/ is a great resource and it's completely free, everything you need to know to build a website is on that page if you have the drive to learn it. Best of luck to you!
Here's a neat roadmap too, in case you find yourself lost on what to learn next https://roadmap.sh/frontend
I recommend JavaScript to build your first website, for both FrontEnd and BackEnd , even tho I am a BIG fan of C++ it is not well suited yet to create websites, and Python would be just as good for the BackEnd as JavaScript but having everything written in only one language will make your learning curve way easier, so it is easy to recommend JavaScript.
Python is an easy and beginner-friendly language. As you've mentioned about Online Clothing store, you'll need to deal with the website part and you'll need Javascript to make the site accessible and functional. Javascript will be more easy to learn if you learn Python first, so you can just start with Python.
I have worked with all these a ton. I make ecommerce and enterprise apps now. The only one of these you need is JavaScript. You can use JS on the backend as Node.js in AWS Lambda. You will need HTML and CSS skills, as well as a database. I recommend MongoDB. Please forget about C++ until you built your first company. Python fits the same purpose as Node.js but is currently popular in the Data Science community so skip it until you have a LOT of customers.
Hello Rachel, as a fellow programmer, I am glad that you are planning on expanding your coding knowledge and skills.
I recommend learning python first as it has a very simple syntax (syntax is how your code looks and how simple it is to type) and is also very user-friendly. Once you get to know how to code in python, you can use this thing called Flask.
Flask is what you call a "web application framework" or a WAF, it basically is a tool used to develop websites and other similar things. You don't have to worry much about it's difficulty because it is based on python. You will still have to learn how to use Flask though as it could be a bit complicating in first glance.If you are looking for simpler ways for making website without having to learn a lot of programming, you can learn HTML and CSS. These 2 will help you in making a basic and functional website. The catch is, from a career perspective, HTML won't get you far, as literally every programmer knows it. So it is best to use programming languages.
I hope this gave you a clear understanding of the ways in which you can build websites. Wishing you the best of luck!
Since you're new, I'd recommend Javascript and Python. With Javascript, just learn React and Node. And with Python, learn Django. With JavaScript, Node, React, Python, and Django; you can accomplish quite a lot for both frontend and backend.
Hi, When saying that "Suppose my goal is to build an online clothing store or something", I would go for a ready to use platform like Wordpress. it will give you a fast jump into the online world. By using WP you'll have to catch on with PHP\JQuery Goodluck.. Ping me when store is ready, I might buy something....
A developer and project manager from our team X says the following about our use of Rails at i22:
"We use Rails to build stable and flexible backend systems. Rails is extremely good for managing data structures and quickly setting up new systems. It is the perfect base for most use cases."
I asked the same Team X member why the team prefers to work with Ruby on Rails, rather than Python and Django:
"Because Python is a scripting language and from my point of view not suitable for building stable web services. Python is for me rather good for scripts and fast small tools. Not for stable business applications. And if I want it fast I prefer Go."
I had a goal to create the simplest accounting software for Mac and Windows to help small businesses in Canada.
This led me to a long 2 years of exploration of the best language that could provide these features:
- Great overall productivity
- International wide-spread usage for long-term sustainability and easy to find documentation
- Versatility for creating websites and desktop softwares
- Enjoyable developper experience
- Ability to create good looking modern UIs
- Job openings with this language
I tried Python, Java, C# and C++ without finding what I was looking for.
When I discovered Javascript, I really knew it was the right language to use. Thinking of this today makes me realize even more how great a decision this has been to learn, use and master Javascript. It has been a fun, challenging and productive road on which I am still satisfied.
Obviously, when I refer to Javascript, it is not without implying the vast ecosystem around it. For me, JS is a whole universe in which almost every imaginable tools exist. It's awesome - for real. Thanks to all the contributors which have made it possible.
To be even clearer about how intense I am with Javascript, let's just say that my first passion was music. Until, I find coding with Javascript! Yep, I know!
So in conclusion, I chose Javascript because it is versatile, enjoyable, widely used, productive for both desktop softwares and websites with ability to create modern great looking user interfaces (assuming HTML and CSS are involved) and finally there are job openings.
Python has become the most popular language for machine learning right now since almost all machine learning tools provide service for this language, and it is really to use since it has many build-in objects like Hashtable. In C, you need to implement everything by yourself.
C++ is one of the most popular programming languages in graphics. It has many fancy libraries like eigen to help us process matrix. I have many previous projects about graphics based on C++ and this time, we also need to deal with graphics since we need to analyze movements of the human body. C++ has much more advantages than Java. C++ uses only compiler, whereas Java uses compiler and interpreter in both. C++ supports both operator overloading and method overloading whereas Java only supports method overloading. C++ supports manual object management with the help of new and delete keywords whereas Java has built-in automatic garbage collection.
I was considering focusing on learning RoR and looking for a work that uses those techs.
After some investigation, I decided to stay with C# .NET:
It is more requested on job positions (7 to 1 in my personal searches average).
It's been around for longer.
it has better documentation and community.
One of Ruby advantages (its amazing community gems, that allows to quickly build parts of your systems by merely putting together third party components) gets quite complicated to use and maintain in huge applications, where building and reusing your own components may become a better approach.
Rail's front end support is starting to waver.
C# .NET code is far easier to understand, debug and maintain. Although certainly not easier to learn from scratch.
Though Rails has an excellent programming speed, C# tends to get the upper hand in long term projects.
I would avise to stick to rails when building small projects, and switching to C# for more long term ones.
Opinions are welcome!
We have a lot of experience in JavaScript, writing our services in NodeJS allows developers to transition to the back end without any friction, without having to learn a new language. There is also the option to write services in TypeScript, which adds an expressive type layer. The semi-shared ecosystem between front and back end is nice as well, though specifically NodeJS libraries sometimes suffer in quality, compared to other major languages.
As for why we didn't pick the other languages, most of it comes down to "personal preference" and historically grown code bases, but let's do some post-hoc deduction:
Go is a practical choice, reasonably easy to learn, but until we find performance issues with our NodeJS stack, there is simply no reason to switch. The benefits of using NodeJS so far outweigh those of picking Go. This might change in the future.
PHP is a language we're still using in big parts of our system, and are still sometimes writing new code in. Modern PHP has fixed some of its issues, and probably has the fastest development cycle time, but it suffers around modelling complex asynchronous tasks, and (on a personal note) lack of support for writing in a functional style.
We don't use Python, Elixir or Ruby, mostly because of personal preference and for historic reasons.
Rust, though I personally love and use it in my projects, would require us to specifically hire for that, as the learning curve is quite steep. Its web ecosystem is OK by now (see https://www.arewewebyet.org/), but in my opinion, it is still no where near that of the other web languages. In other words, we are not willing to pay the price for playing this innovation card.
Haskell, as with Rust, I personally adore, but is simply too esoteric for us. There are problem domains where it shines, ours is not one of them.
In 2015 as Xelex Digital was paving a new technology path, moving from ASP.NET web services and web applications, we knew that we wanted to move to a more modular decoupled base of applications centered around REST APIs.
To that end we spent several months studying API design patterns and decided to use our own adaptation of CRUD, specifically a SCRUD pattern that elevates query params to a more central role via the Search action.
Once we nailed down the API design pattern it was time to decide what language(s) our new APIs would be built upon. Our team has always been driven by the right tool for the job rather than what we know best. That said, in balancing practicality we chose to focus on 3 options that our team had deep experience with and knew the pros and cons of.
For us it came down to C#, JavaScript, and Ruby. At the time we owned our infrastructure, racks in cages, that were all loaded with Windows. We were also at a point that we were using that infrastructure to it's fullest and could not afford additional servers running Linux. That's a long way of saying we decided against Ruby as it doesn't play nice on Windows.
That left us with two options. We went a very unconventional route for deciding between the two. We built MVP APIs on both. The interfaces were identical and interchangeable. What we found was easily quantifiable differences.
We were able to iterate on our Node based APIs much more rapidly than we were our C# APIs. For us this was owed to the community coupled with the extremely dynamic nature of JS. There were tradeoffs we considered, latency was (acceptably) higher on requests to our Node APIs. No strong types to protect us from ourselves, but we've rarely found that to be an issue.
As such we decided to commit resources to our Node APIs and push it out as the core brain of our new system. We haven't looked back since. It has consistently met our needs, scaling with us, getting better with time as continually pour into and expand our capabilities.
In December we successfully flipped around half a billion monthly API requests from our Ruby on Rails application to some new Python 3 applications. Our Head of Engineering has written a great article as to why we decided to transition from Ruby on Rails to Python 3! Read more about it in the link below.
When I was evaluating languages to write this app in, I considered either Python or JavaScript at the time. I find Ruby very pleasant to read and write, and the Ruby community has built out a wide variety of test tools and approaches, helping e deliver better software faster. Along with Rails, and the Ruby-first Heroku support, this was an easy decision.
As a personal research project I wanted to add post-quantum crypto KEM (key encapsulation) algorithms and new symmetric crypto session algorithms to openssh. I found the openssh code and its channel/context management extremely complex.
Concurrently, I was learning Go. It occurred to me that Go's excellent standard library, including crypto libraries, plus its much safer memory model and string/buffer handling would be better suited to a secure remote shell solution. So I started from scratch, writing a clean-room Go-based solution, without regard for ssh compatibility. Interactive and token-based login, secure copy and tunnels.
Of course, it needs a proper security audit for side channel attacks, protocol vulnerabilities and so on -- but I was impressed by how much simpler a client-server application with crypto and complex terminal handling was in Go.
