Simple Program for Static Data and Member Function Using C++ Programming

Aim

To count the object value using the storage keyword static.

Static Data and Member Function Algorithm/Steps:

• STEP 1:  Start the program.
• STEP 2:  Declare the class name as Stat with data members and member functions.
• STEP 3:  The constructor Stat() which is used to increment the value of count as 1 to assign the variable code.
• STEP 4:  The function show code() to display the code value.
• STEP 5:  The function showcount() to display the count value.
• STEP 6:   Stop the program.

Simple Program for Static Data and Member Function

#include<iostream.h>
#include<conio.h>

class stat {
    int code;
    static int count;

public:

    stat() {
        code = ++count;
    }

    void showcode() {
        cout << "\n\tObject number is :" << code;
    }

    static void showcount() {
        cout << "\n\tCount Objects :" << count;
    }
};

int stat::count;

void main() {
    clrscr();
    stat obj1, obj2;

    obj1.showcount();
    obj1.showcode();
    obj2.showcount();
    obj2.showcode();
    getch();
}

Sample Output

Count Objects: 2
Object Number is: 1
Count Objects: 2
Object Number is: 2
