A static member function is a special member function, which is used to access only static data members, any other normal data member cannot be accessed through static member function. Just like static data member, static member function is also a class function; it is not associated with any...
Logic to count the created objects using static member functionThis program is implemented to count the total number of created objects with the help of static data member and static member function.A static data member needs to be declared first that we declared in private section: Example: ...
class Screen{ public: //bkgroundrefers to the static member declared later in the class definition Screen& clear(char = bkground); private: static const char bkground = '#'; }; <C++Primer>是这样解释的: Anonstatic data member may not be used as a default argument becauseits value cannot...
C++ Static Members - Learn about static members in C++, including static data members and static member functions, and their significance in object-oriented programming.
The static member function(s) is similar to the normal member function(s) of a class, but the only difference is that it can access only static member(s) (data or functions) declared in the same class. In other words, we cannot access non-static members inside the definition of a ...

Inside the body of an explicit object member function, thethispointer cannot be used: all member access must be done through the first parameter, like in static member functions: structC{voidbar();voidfoo(this C c){autox=this;// error: no thisbar();// error: no implicit this->c.bar...
A static member function can access only the names of static members, enumerators, and nested types of the class in which it is declared 01 class X{ 02 public: 03 int b; 04 static int a; 05 enum mode{a1,a2,a3}; 06 static int inc() 07 { 08 return a1; //this is allowed sinc...
#include <bits/stdc++.h> using namespace std; class Base { public: static int val; // Static variable static void func(int a) { // Static member function cout << "\nStatic member function called"; cout << "\nThe value of a: " << a; } }; // Definition of the static variab...
