This may fall under the heading of "Don't do that" but did cause me to be slightly curious.<BR><BR>What would happen if you say, created a pointer to a function that took three ints as arguments ...

Listing 2 shows a typical functor. Unlike C pointers to functions, functors can keep state (i.e., in private member variables, as you'll see in Listing 3). The downside compared with C comes from all ...
