Write a program in C++ to implement static member function in class.

Write a program in C++ to implement static member function in class.

Algorithm to solve the above problem:

1. Create class count with static data member as total.

2. Create a member function to increment the count.

3. Declare the static data member using scope resolution operator.

4. Display the count and total value.

Implementation of the above problem in C++:

#include<iostream>

using namespace std;

class count

{

private:

int number;

static int total;

public:

count();

int get_number();

static int get_total();

};

count::count()

{

number=100+ total++;

}

int count::get_number()

{

return number;

}

int count::get_total()

{

return total;

}

int count::total=0;

int main ()

{

cout<<" Total count = "<<count::get_total() <<endl;

count a, b, c;

cout<<" a="<<a.get_number() << endl;

cout<<" b="<<b.get_number() << endl;

cout<<" b="<<c.get_number() << endl;

cout<<" Total count="<<count::get_total() << endl;

return 0;

}

The output of the above program is tested on www.jdoodle.com

Output:

Total count = 0

a=100

b=101

c=102

Total count = 3
