Static Member Functions

Like static member variable, we can also have static member functions. A member function that is declared static has the following properties:

? A static function can have access to only other static members declared in the

  same class.

? A static member function can be called using the class name as follows:

                    Class-name :: function -name;

The general syntax for defining static member function is

Static return_type function-name(arguments)

{

function body;

}

Sample Program

#include <iostream.h>

Class test

{

int code;

static int count;

public:

void setcode(void)

{

code = ++count;

}

void showcode(void)

{

cout<<”Object number “<<code<<endl;

}

static void showcount(void)

{

cout<<”count is “<<count<<endl;

}

};

int test::count;

void main()

{

test t1,t2;

t1.setcode();

t2.setcode();

test::showcount();

test t3;

t3.setcode();

test::showcount();

t1.showcode();

t2.showcode();

t3.showcode();

}
