AIM:

          To write a C++ program using static data member and static member function.

ALGORITHM:

STEP 1: Start the program.

STEP 2: Declare static variable ‘count’.

STEP 3: Define static variable ‘count’ outside of the class.

STEP 4: Define member function ‘show count()’ for displaying the value of count.

STEP 5: Call the static function in main function.

STEP 6: Stop the program.

PROGRAM CODE:

#include<iostream.h>
#include<conio.h>
class test
{
    int code;
    static int count;
    public:
    void setcode()
    {
        code=++count;
    }
    void showcode()
    {
        cout<<"n  Code = "<<code<<"n";
    }
    static void showcount()
    {
        cout<<"n  Count = "<<count;
    }
};
int test::count=0;
void main()
{
    clrscr();
    test t1;
    t1.setcode();
    t1.showcode();
    t1.showcount();
    getch();
}

OUTPUT:

RESULT:

                 Thus the C++ program using static data member and static member function is written and executed successfully.
