3. Constructors

3. Constructors

Constructors are special functions in classes automatically invoked during object creation to initialize objects. They can be parameterized or non-parameterized, allowing flexibility in initializing object properties. Constructor overloading enables defining multiple constructors in a class with different parameter specifications, enhancing code clarity and maintenance.

What we have learnt

  • A constructor is a special function that initializes an object when it is created.
  • Constructors share the same name as the class and do not have a return type.
  • Different types of constructors (default, parameterized, and overloaded) provide various means to initialize object properties.

Key Concepts

-- Constructor
A special function in a class that is invoked at the creation of an object to initialize its properties.
-- Default Constructor
A constructor that does not take any parameters and provides default values.
-- Parameterized Constructor
A constructor that takes parameters to initialize an object with specific values.
-- Constructor Overloading
The ability to have multiple constructors in a class with different parameter lists to enable flexibility.
