this warning is due to type mismatch, function that you were calling returns int and function that you have defined returns void..

That is a problem. If you dont use void, by default function will return integer, so there will not be any warning.

cheers..!!

If the function name appears before its declaration, C compiler will follow certain rules and makes the declaration itself. If it is wrong, you will get that error.

You have two options: (1) define it before you use it, or (2) use forward declaration without implementation
