IMPLEMENTATION OF STATIC MEMBERS

Aim:

To write a C++ program to demonstrate the static members

Algorithm:

Step 1: Start the program.

Step 2: Create a class with static data members and static function.

Step 3: The static value is initialized to zero during object creation. The static value is incremented when a member function set is called for every object.

Step 4: We can also reinitialize the static member value during the static member definition.

Step 5: The result is displayed.

Step 6: Stop the process.

Program:

#include<iostream.h>

#include<conio.h>

class staticmember

{

 int a;

 static int count,cnt;

 public:

       void set()

       {

        a=++count;

        cnt++;

       }

       void show()

       {

            cout<<"\n";

            cout<<"Object Number:"<<a<<"\n";

       }

       static void showcount()

       {

         cout<<"Static count value:"<<count<<"\n";

         cout<<"Static cnt value:"<<cnt<<"\n";

       }

};

int staticmember::count;

int staticmember::cnt = 100;

void main()

{

  staticmember s1,s2,s3;

  clrscr();

  s1.set();

  s1.show();

  cout<<endl;

  s2.set();

  staticmember::showcount();

  s2.show();

  cout<<endl;

  s3.set();

  staticmember::showcount();

  s3.show();

  cout<<endl;

  getch();

}

Output:

Object Number:1

Static count value:2

Static cnt value:102

Object Number:2

Static count value:3

Static cnt value:103

Object Number:3

Result:

Thus the C++ program was executed and the output is verified.
