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.
