Prog 25 Write a program for a  static member can be used as a counter that count a record  occurance of all the object.



#include<iostream.h>

  #include<conio.h>

  class item

{

public:

static int count;

  int no;

void getdata(int a)

{

no=a;

  count++;

  }

  void display()

  {

  cout<<"\n count  ="<<count;

  }

  };

  int item::count;

  void main()

  {

  clrscr();

item A,B,C;

A.display();

B.display();

C.display(); 

A.getdata(100);

A.display();

B.getdata(200);

B.display();

C.getdata(300); 

C.display();

getch();

  }

Output:

count =0 count =0 count  =0 count =1 count =2 count =3
