Using a member function pointer within a class

Question

Given an example class:

{
public:
Fred() 
{
    func = &Fred::fa;
}

void run()
{
     int foo, bar;
     *func(foo,bar);
}

double fa(int x,          


        

Answer 1

A member function with two args is really a three arg function. 'this' is an implicit argument so the error you are getting is about missing the 'this' arg.
