How do I declare, assign and call a pointer to a method?
Note that a pointer to a method does not hold a second pointer to an instance of a
class. To use a pointer to a method, you need an instance of the class onto which this
method can be called (possibly a second pointer).
struct A
{
void m(int) {}
};
void function()
{
void (A::*pm)(int) = &A::m; // pointer on method
A a; // instance of a class
(a.*m)(1); // calling the method with parameter value 1.
}
