A member function with the same name as its class is called a constructor. 

A constructor defines a way to initialize an object of its class.

A constructor is similar to a function, but with the following differences.

• No return type
• No return statement

class Point 

{
    public:
        Point();  // parameterless default constructor
        Point(int new_x, int new_y); //  constructor with parameters
        int getX();
        int getY();
    private:
        int x;
        int y;
};

Point::Point()   // default constructor

{

    x = 0;
    y = 0;
}
