I looked over other forums and couldn't find the answer to this. C++ defines a void type for functions, which denotes no return value. If this was not available, what alternatives could be used?

well you can always return a bool which is 1 bit so itll be best alternative to void.
im pretty sure there isnt anything else like void.

Thank you very much Mrafcho001. That should be the only alternative to void.

Actually, even when you mention void, internally the function main() does return a value to it's calling function 'start()' (In Windows)
The value of the EAX register is set to zero before main() exits.
This return value is used to decide how the program terminates.

So even returning zero from main() is an equivalent of returning nothing using void.

Actually, since the EAX register is almost always used to return values from all functions, my statement is valid for almost all functions.
