getch and clrscr are not part of the C Standard Library. Where do this functions come from? You should have gotten a header file from whereever those functions came from.

You need to include conio.h to get the getch prototype. You may need to use _getch since the name getch is deprecated.

clrscr is non-standard. I recommend you use the system function:

system("cls");

You will need to include <stdlib.h> to use the system function
