Create a simple game with C program.
If you have problem with the library conio2.h you have to download it. If you have still problems set on compiler settings->linker the string "-lconio".

If you have problem with the library conio2.h you have to download it. If you have still problems set on compiler settings->linker the string "-lconio".
