What? is Constructor in one video .

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.
