I was wondering if there was an easier way to overload a function to accept different types of data (int, float), when the type wouldn''t matter. An example of this would be a memory manager, you have a DeAllocate() function, no matter what type of pointer is passed, you want to just delete it, and it won''t matter what type. (this is assuming no arrays)

Um, templates?

template <class T>void DeAllocate(T* ptr){   delete ptr;}

Thank you very much Desert Fox!! I knew I had read about something like this somewhere, and I was looking through my unorganized tutorials and I couldn''t find it.

And possibly another good solution would be using a void *, which accepts any datatype (and furthermore you could cast them to an int, float, etc)

void DeAllocate(void *ptr){       delete ptr;}

Except in that case a destructor never gets called if ptr points to an object and not a primitive =)
