How to run c language code

To run C language code, you need to perform the following steps: Install the C language compiler. Use a text editor to write the code and save it in a file. Use a compiler to compile the code to produce an executable file. Run the executable file to execute the code.

How to run C language code

Step 1: Install the compiler

First, you need to install a C language compiler. Commonly used compilers include GCC (Linux and macOS), Visual Studio (Windows), and Clang (all platforms).

Step 2: Write the code

Using a text editor or integrated development environment (IDE), write the C language code and save it in a file, such as " hello.c".

Step 3: Compile the code

Use a compiler to compile the code. In the command prompt, navigate to the directory containing the C language code and enter the following command:

<code>gcc hello.c -o hello</code>

This will compile the code and generate an executable file "hello".

Step 4: Run the executable file

To run the executable file, enter the following command in the command prompt:

<code>./hello</code>

Code example:

The following is a simple C language code example:

#include <stdio.h>

int main() {
    printf("Hello, world!\n");
    return 0;
}

Execution steps:

1. Change the above code Paste into a file called "hello.c".
2. Compile code:<code>gcc hello.c -o hello</code>
3. Run the executable file:<code>./hello</code>
4. The output will be Display "Hello, world!".
