Syntax

Assuming a class named Class:

• type *ptr = &Class::member; // Point to static members only
• type Class::*ptr = &Class::member; // Point to non-static Class members

For pointers to non-static class members, given the following two definitions:

Class instance;

• Class *p = &instance;

Pointers to Class member variables

• ptr = &Class::i; // Point to variable i within every Class
• instance.*ptr = 1; // Access instance’s i
• p->*ptr = 1; // Access p’s i

Pointers to Class member functions

• ptr = &Class::F; // Point to function ‘F’ within every Class
• (instance.*ptr)(5); // Call instance’s F
• (p->*ptr)(6); // Call p’s F
