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.

You may declare functions in many places other than the standard areas (remember declaring is a very simple hint, not a definition of the function), although that is a very poor programming method. Correct or not, headers are usually the correct place to store these declarations.

Also you can declare a function with any prototype any where though as already mentioned by Alexander, the only correct way to do this is to use header files.

So

 void func(void); 

Can be placed any where inside main, before main or after main (if it is not called in main)
