Types of Constructor:
1. Default constructor:
Note: A constructor used to initialize the instance variables with default initial values, is known as Default Constructor. When no constructor is defined in a program, the compiler creates a constructor on its own. As soon as an object of a class is created, it uses this constructor to initialize the instance variables with system approved initial values.
2. Non-parametrized constructor:
Note: A non-parameterized constructor initializes instance variables with default values and is defined with an empty parameter list (e.g., n_pconst()). Here, the object can be created in two ways Created by compiler and Created by programmers
3. Parameterized Constructor:
Note: A function with the same name as that of a class name can be used to initialize the instance variables of the object with the values provided through parameter list. The instance variables are initialized with the parametric values passed while creating an object. Such a constructor is known as a parameterized Constructor.
3. Copy Constructor:
Note: A constructor that is used to initialize the instance variables of an object by copying the initial values of the instance variables from another object, is known as Copy Constructor. It can be done via two methods:
- Direct entry copy constructor: In this system, the initial value of an object is copied by assigning it to another object.
- Copy constructor by passing object: In this system, object is passed to the constructor. Further, the instance variables of the current object (i.e., the object through which the constructor is called) are initialized by copying the values from object passed to the constructor.
