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.
