what member function

In STL algorithms, function pointers and function-like passing algorithms can be used. So why do we still need regular function adapters? Because regular function adapters do not have the "matching capability" Example: /** File: Main. CPP * Author:

1. prototype of the string-type member function c_str: Const char * c_str () const; // returns a null-terminated C string.   2. the c_str () function returns a pointer to a regular C string. The content is the same as the object of the string

It means that the initialize () member function of Class A cannot be called without an object (); Context: Void B: Initialize (INT argc, char ** argv) { ··· A: Initialize (argc, argv ); ··· } Modification method: 1. Class B inherits Class

Standard C ++ does not have real Object-Oriented function pointers. This is a pity, because Object-Oriented function pointers (sometimes called delegates) have proved their value in other languages. In Delphi (Object-Oriented PASCAL Language),

In programming, we often encounter the requirement to call member functions through function pointers in a "class". For example, when a class is usedC ++When the sorting function qsort in the standard library requires a "comparison function" pointer
