4.4 Pointer to Member function (Pointer-to-member Functions)take a nonstatic data member address, the result is the member in the class layout of the byte position (plus 1), it is an incomplete value, need to be bound to the address of a class object, to be able to be accessed.take the address of a nonstatic member function, and if the function is nonvirtual, the result is a real address in memory. However,
