Static Member Functions

You cannot have static and nonstatic member functions with the same names and the same number and type of arguments.

A static member function does not have a this pointer. You can call a static member function using the this pointer of a nonstatic member function. In the following example, the nonstatic member function printall() calls the static member function f() using the this pointer:

// This example illustrates a static member function f().

#include <iostream.h>
class c {
            static void f() { cout << "Here is i"
                                        << i << endl;}
            static int i;
            int j;
      public:
            c(int firstj): j(firstj) {}
            void printall();
            };
void c::printall() {
      cout << "Here is j " << this->j << endl;
      this->f();
      }
int c::i = 3;
void main() {
      class c C(0);
      C.printall();
      }

A static member function cannot be declared with the keyword virtual.

A static member function can access only the names of static members, enumerators, and nested types of the class in which it is declared.
