Constructor – Description in Points
Definition:
A constructor is a special type of function that is automatically called when an object of a class is created.

Purpose:
Its main role is to initialize objects. It sets up the initial state or assigns default or given values to variables in the object.

Name Rule:
The name of a constructor is same as the class name.

No Return Type:
A constructor does not have a return type, not even void.

Automatic Call:
You don’t need to call a constructor manually—it runs automatically when an object is created.

Types of Constructors:

Default Constructor: Takes no arguments and initializes values with defaults.

Parameterized Constructor: Takes arguments to set specific initial values.

Copy Constructor: Creates a new object using an existing object.

One-Time Use per Object:
A constructor is called only once per object, at the time of its creation.

Supports Overloading:
You can have multiple constructors with different parameters (constructor overloading).

Used in OOP:
Constructors are a key part of object-oriented programming (OOP), helping to manage data within objects.

Helps in Clean Code:
By using constructors, object creation and setup become clean, organized, and less error-prone.
