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.

So, you can modify this statment to: if(strcmp(name,"Yousef") != 0) printf("name undefined\n");

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

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");

Attention: Include string libreary after using these functions to skip any problem may be found.

may Allah bless you ^_^

Native apps are not going to die. Especially not Swift because now Swift can be used to develop cross platform macOS and iOS apps due to the new macs having M1 chips.

"Should I just learn Swift first due to the pros of the native apps?". React Native builds Native Apps. Technologies like ionic does NOT build native apps, but React Native does it.

Learning Swift seems to be a really bad idea from my point of view. Learning JavaScript is all what you need. Why? Because then Frontend, Backend, and Mobile Dev, is simple, because it's all JavaScript.

If asking about employment opportunities, native will never die out. There will always be opportunity for work in native mobile applications. There are also many advantages of using native over cross platform such as always having access to the latest APIs and developer libraries that may not be available to cross-platform without some native development involved or can wait until someone develops a bridge for you.

If you are asking about what you should develop with first? It really depends. React-Native is great for building proto-types or basic MVP application that doesn't require any of the latest and greatest features Apple has to offer at the moment. But if you're asking what to learn? I would say native will always give you a larger advantage as it will give you a good foundation in mobile development and provide you access to the latest native libraries. It is also a useful skill that can give you an edge in cross-platform mobile like react-native because you will most definitely encounter a situation where you will have to go down to the to native side to extend functionality or utilize APIs that are not yet out of the box.

I would suggest to bet more on Swift! I have developed act in React and Javascript in the past and played around with Swift a little... the performances of native code vs Javascript are way too slow compared to swift native app!

Now even more than ever M1 chip will give a boost, but if it gives a boost to JS it will give a boost also to native apps. I would seriously consider Swift more than Javascript, React or even Electron!

The decision comes down to your goals and needs.

If you want to be able to create any kind of iOS app, simple or complex, learn Swift. It's indispensable if you're building specialised apps like video editing, augmented reality, machine learning or anything that uses iOS-specific APIs such as App Clips.

But if you just want to create apps that make HTTP requests and display static content such as text or basic video and music, React Native would do just fine, and you can publish the same code to Android. This is a no-brainer choice if you're on a low budget.

And if you know both, you can use both in the same app. You can add React Native screens or components inside a Swift app.

Mobile Native Development Apps will never die. Cross Plataform like React Native only exists to save time and costs for startups mainly, which is extraordinary, and indispensable often of course. But when the App get popular enough, it will probably will move to Native Development. Several improvements.

Less than 20% of the market is IOS, the rest is Android. Any developer must produce for Android and maybe support IOS. If you prototype on IOS you have to restart again for Android. React and JavaScript will run on IOS.
