Thread: where to make function declaration, before main( ), or within main( )?

Hi

So far I have always seen function declarations of user-defined functions being made before the main( ). But I have seen someone who made the declaration within the main( ) for a functions which returns a value? Is this correct? Can we also do this for functions which returns nothing - I mean of void return type?

I don't have a compiler on my computer right now so can't test it? Please help me. Thanks.

It's nothing to do with what type the function returns.

You can add a function prototype declaration at the start of any scope opening brace. It's not illegal, just weird.

I was taught to have the prototype before main..as in
int max(int x, int y);
int min(int x, int y);
then have the definition after main's body

Code:

int main()
{
}
int max(int x, int y)
{
}

IMO i think that is easier to read if people do it like my lecturer said...A classmate was asking me to read her code..when I saw a function declared and defined in main() itself..I just wanted to cry then go to sleep.
