CodeLite cmd promt closing immediatly after execution of code

Question

I run the simplesest c hello world function in codelite just to see it works well

void main ( )
{
    
    printf("hello world\n");
    
}

the cmd promt opens for q brief momet and then closes down immediatly.

what's wrong and how can I keep the cmd prompt without closing?

I excepct for the cmd prompt to stay

Two choices: a) open a command prompt first and run the code from there, or b) if running from IDE add an input to the end of the code, such as `getchar();` and then press Enter to end the program. — Weather Vane, Jan 13 '23 at 11:33

From C11:

If the return type of the main function is a type compatible with int, a return from the initial call to the main function is equivalent to calling the exit function with the value returned by the main function as its argument; reaching the } that terminates the main function returns a value of 0. If the return type is not compatible with int, the termination status returned to the host environment is unspecified.

After the call to printf; control reaches the closing brace }, terminates main, and thus returns to the host environment with an exit status of EXIT_SUCCESS, or 0.

Also note that it states:

The function called at program startup is named main. The implementation declares no prototype for this function. It shall be defined with a return type of int and with no parameters:

int main (void) { /* ... */ }

or with two parameters (referred to here as argc and argv, though any names may be used, as they are local to the function in which they are declared):

int main (int argc, char *argv[]) { /* ... */ }

or equivalent; or in some other implementation-defined manner.

You did not mention your OS, so I will assume Windows. Like other people mentioned, unless you add a call to getchr() or something similar, this is the expected behavior.

However, CodeLite does offer an option to pause your program once the execution is done.

Right click on your project and open the settings
Under the General tab, in the Execution section, make sure to check the option: Pause when execution ends (see attached screenshot)

What this does: Instead of running your program directly, CodeLite executes a small wrapper that will execute your program, and that wrapper pauses when its done.
