Study Notes

Inheritance in C++

  • A base class in C++ is a class from which other classes can inherit its properties and behavior.
  • The main advantage of using inheritance in object-oriented programming is code reuse, which allows developers to create a new class based on an existing class, reducing redundancy and increasing efficiency.

Inheritance Problem Solving

  • Inheritance solves the problem of code duplication in object-oriented programming by allowing developers to create a new class that is a modified version of an existing class.

Derived Class

  • A derived class in C++ is a class that inherits properties and behavior from a base class, also known as a subclass or a child class.

Disadvantages of Inheritance

  • The main disadvantage of inappropriate use of inheritance in object-oriented programming is tight coupling, where a change in the base class can affect all derived classes, making it difficult to maintain and modify the code.
