Question

   // istead of :) i want to have an emoji added to my text.

  printf("Thank you for looking into my question :) ");

  return 0;

You look up the unicode code for the emoji of interest, prefix the code with the universal character name \U when printing:

#include <stdio.h>

int main() {
    printf("%s", "\U0001f600"); // :-)
    return 0;
}

Your terminal must support unicode and the font you use must have a glyph defined for the emoji.
