5 Questions
In object-oriented programming, what is inheritance?
The mechanism of basing an object or class upon another object or class, retaining similar implementation
What does a 'child object' acquire from a 'parent object' in inheritance?
All the properties and behaviors, except constructors, destructors, overloaded operators, and friend functions
What is one of the main benefits of inheritance in object-oriented programming?
Reuse code and create classes built upon existing classes
What is not inherited by a 'child object' from a 'parent object' in most class-based object-oriented languages like C++?
Constructors, destructors, overloaded operators, and friend functions
What does inheritance allow programmers to do with existing classes and interfaces?
Independently extend original software via public classes and interfaces
Study Notes
Inheritance in Object-Oriented Programming
- Inheritance is a mechanism where a new class, the child or subclass, inherits the properties and behavior of an existing class, the parent or superclass.
- A child object acquires all the fields and methods of the parent object, which enables code reuse and facilitates a more hierarchical organization of code.
Benefits of Inheritance
- One of the main benefits of inheritance is code reuse, as a child class can reuse the code from the parent class and build upon it.
Limitations of Inheritance
- A child object does not inherit the private members (methods and variables) of the parent object in most class-based object-oriented languages like C++.
Advantages of Inheritance in Programming
- Inheritance allows programmers to create new classes and interfaces that build upon existing ones, facilitating the creation of complex systems and promoting software development efficiency.
