// Intrduction of Constructor

// Constructor is a special member function of a class which is used to initialize the objects of its class.

// It is special because its name is the same as the class name.

// It is invoked whenever an object of its associated class is created.

// It is constructor’s responsibility to initialize the object of its class.

// It has no return type, not even void.
