C++ Program to increment the number to show the working of static function

Program -

#include<iostream.h>

#include<conio.h>

#include<dos.h>

class stu

{

private:

static int c;

public:

stu();

static void write();

};

int stu::c=0;

stu::stu()

{

c++;

}

void stu::write()

{

cout<<"final value of c"<<c<<endl;

}

void main()

{

cout<<"before understanding object"<<endl;

stu::write();

stu m1,m2,m3,m4,m5;

cout<<"after the understanding of object"<<endl;

stu::write();

getch();

}

 

Output :

  

before understanding object

final value of c 0

after the understanding of object

final value of c 5
