Inheritance in object-oriented programming is a mechanism where a class (subclass) is derived from another class (superclass), allowing it to retain similar implementations. This forms a hierarchy of classes. In class-based languages like C++, a subclass inherits properties and behaviors from its parent class but does not inherit constructors, destructors, overloaded operators, or friend functions. Inheritance enables code reuse, new implementations while preserving behaviors, and independent software extensions via public classes and interfaces. While the term "inheritance
