How to run C language program code

Steps for running C language program code

Step 1: Compile

• Use a compiler (such as GCC or Clang ) Translate C language code into machine code and generate executable files.
• The main task of the compiler is to check for syntax errors and generate object code.

Step 2: Linking

• If the program uses external libraries or functions, the linker links these codes into the executable file.
• This process ensures that all required code is in the executable file.

Step 3: Execution

• The operating system loads the executable file and starts execution.
• The program starts execution from the entry point main() function.
• The code is executed sequentially until a return statement is encountered or the end of the program is reached.

Detailed steps:

1. Edit C language code: Use a text editor or IDE (such as Visual Studio Code) to write C language code. Make sure your code is syntactically correct.

2. Compile the code: Use the compiler command on the command line to compile the code. For example, for the GCC compiler:

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

3. Run the executable file: After successful compilation, enter the executable file name on the command line to run the program. For example:

<code>./my_program</code>

Additional notes:

• Additional flags or options may need to be specified when compiling, depending on the needs of the program.
• Programs may require input or access to external files.
• The running time and memory usage of C language programs depend on the algorithm and code complexity.
