Function Declaration / Function Definition

Question

Does it matter if the function definition is before int (main) or after int main?

I have seen this in both directions and am trying to find the right way to display function definitions and declarations.

Answer 1

No, it is not. This is a matter of preference. Choose which you prefer and be consistent!

Answer 2

A function definition (which contains the actual code) can be anywhere, even in another file, until a declaration (function prototype) appears before the function is called.

Answer 3

Answer 4
