Code​

Practical-09.cpp


#include <iostream>

// A static member function can only access static data members
// and other static member functions of a class
class Student
{
private:
    // static data member
    static int studentCount;

public:
    // Constructor to increment student count
    Student()
    {
        studentCount++;
    }

    // static member function
    static int getStudentCount()
    {
        return studentCount;
    }
};

// static data member initialization
int Student::studentCount = 0;

// main function
void main()
{
    Student s1;
    Student s2;

	// calling static member function
    int studentCount = Student::getStudentCount();

     // printing student count
    std::cout << "Student count is: " << studentCount;
    return 0;
}

Output​

Student count is: 2
