}

void main ()
{

	func(10);
	system ("pause");

too much thinking to do :/

http://www.cplusplus.com/doc/tutorial/pointers/ has all the info you need

also you should use a debugger on this programm and just run through, step by step

Why did you make your main a void? You need to make it an int first and have it return 0 (to be "grammatically" correct).

I don't understand what your problem is. Your program is returning a Fibonnaci sequence so it appears to be functioning as normal (assuming that's what you wanted it to do). What are you confused about?
