Object Oriented Programming Using C++(313304) Practical No.10: Write programs for Default Constructor Answer

The classes and objects help to represent real-life entities with different attributes and related member functions. The use of constructor functions facilitates the initialization of instance variables.

Constructor: Constructors are special member functions that perform the initialization of every object. The Compiler calls the Constructor whenever an object is created. Constructors initialize values to instance variables after storage is allocated to the object. Constructors are of three types :

1. Default Constructor

2. Parameterized Constructor

3. Copy Constructor
