What is constructor with example?
When a class or struct is created, its constructor is called. Constructors have the same name as the class or struct, and they usually initialize the data members of the new object. In the following example, a class named Taxi is defined by using a simple constructor. For more information, see Instance Constructors. 3
What is constructor in oops?
In class-based object-oriented programming, a constructor (abbreviation: ctor) is a special type of subroutine called to create an object. It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables. Immutable objects must be initialized in a constructor.
Why do we use constructor?
We use constructors to initialize the object with the default or initial state. The default values for primitives may not be what are you looking for. Another reason to use constructor is that it informs about dependencies.
