#include <stdio.h>

int main(){
    printf("Hello world");
    return 0;
}

Its my first time using c language and setting it up. I already include path for mingw on my windows and i install c/c++ and code runner in my visual studio code.

The code is correct.

You could try to compile it from command line. See what happens

gcc filename.c -o filename

then run it with

./filename

I managed to reproduce the error. Just save the file before using code runner.
