Sample Code for Static Data Member

An Example from our class lecture

// static data

#include<iostream.h>

#include<conio.h>

 

class foo

{

private:

static int t;

int count;

public:

 

    foo()

     {

     t++;

     count = 0;

     }

    int get_cnt()

     {

     return t;

     }

     int get_count()

     {

     return count;

     }

};

 

int foo:: t;

 

void main()

{

 

clrscr();

// cout << "No object of foo created " << foo::t;

 

foo f1, f2, f3;

 

cout << "\nStatic Count is " << f1.get_cnt();

cout << "\nstatic Count is " << f2.get_cnt();

cout << "\nstatic Count is " << f3.get_cnt();

 

cout << "\nCount is " << f1.get_count();

cout << "\nCount is " << f2.get_count();

cout << "\nCount is " << f3.get_count();

 

/* foo f4, f5;

 

cout << "\nCount is " << f4.get_count();

cout << "\nCount is " << f5.get_count();

*/ getch();

}
