Class:A class is a blueprint or template for creating objects in object-oriented programming. Constructors belong to classes and define how objects of that class should be initialized.
Instance variables: Instance variables are attributes or properties associated with each instance (object) of a class. Constructors often assign initial values to these instance variables.
Overloading:Constructor overloading allows multiple constructors within the same class, but with different parameter lists. This provides flexibility in creating objects with varying initialization options.
