Void main is not working in code block compiler.. Why?

Answer 1

If I'm not wrong, you have to use the type "int" for main() function.
Maybe what you want to do is tell the function main() to be void -> main(void). That, you can do in Code::Blocks.

At the end of the main() function, you return a value of 0 or 1, which are integers... that's why you define the function with int type.

Answer 2

but what if we are dealing with function?
