Static Operator in C++ || Operators in C++ || C++

Static Operator in C++ :-

--> Static Operator is an operator which does not require any instance to access it members. For example we have a class, now in order to access the class we create an object / instance to access it and its members, but when we create a static class then we don't have to create any object / instance for it. It can be directly accessed or called.

Static Operator can be used for many things / purposes like there can be a static method (Function), variable or declaration etc.

Static functions are accessed using only the class name and the scope resolution operator " :: ".

A static member function can only access static data member, other static member functions and any other functions from outside the class.

Syntax To Use Static Operator:

    

// Static Function
static void fnc_name()
{
    // Function_Content
} 


// Static Variable
static datatype variable_name

Example to use Static Operator for a function :

    
/*C++ program to print WELCOME TO HFC!!! */
#include<iostream>
#include<stdlib.h>
using namespace std;

class print
{
    public:
    static void show(void)
    {
        cout << "Welcome to HFC!!!";
    }
};

int main(void)
{
    system("cls");
    print::show();
    return 0;
}

OUTPUT:-

  
Welcome to HFC!!!

Example to use Static Operator for a Variable :

    
//C++ program to call and increment COUNT 3 times.
#include<iostream>
#include<stdlib.h>
using namespace std;

class Class
{
    public:
    static int count;
    Class();
};

Class::Class()
{
    count++;
}

int Class::count = 0;

int main(void)
{
    system("cls");
    cout << "Initial value of count:- " << Class::count;
    Class obj1, obj2, obj3;
    cout << "\nCount value after 3 objects:- " << Class ::count;
    return 0;
}

OUTPUT:-

  
Initial value of count:- 0
Count value after 3 objects:- 3

In this post we got to know about Static Operator and it's uses with function and Variable in C++.
