Re: [Dev-C++] Pointer to function

[David M. <dml...@co...>]

int result3 = (instance.*pt2Member)(12, 'a', 'b');    // Outside class
int result4 = (*this.*pt2Member)(12, 'a', 'b');       // Inside class

in your case it would be:
cout << (cA.*pFunc)();

A good tutorial on this topic is avalible @ www.function-pointer.org

Hope this Helps
