C++ OOP Quizzes

Object-Oriented Programming (OOP) in C++ is a programming paradigm based on the concepts like classes, objects, inheritance, polymorphism, and encapsulation. This programming technique allows us to efficient and scalable C++ applications, so, the proper knowledge of these concepts is required to create real-world software.

Quizzes are one of the best and quick way to test your knowledge. This quiz is designed to test your knowledge of important OOP concepts in C++.

C++ OOP Quizzes

The following list contains topic-wise quizzes from Object-Oriented Programming in C++:

• OOP in C+++: This quiz contains 25 questions from basic introduction of OOP.
• Class and Object: Classes are user-defined types, and objects are instances of these classes. This quiz tests your understanding of the basics of class creation and object manipulation using 17 MCQs.
• Constructors: Constructors are special member functions used to initialize objects. This quiz contains 26 MCQs that focuses on types of constructors, overloading, and initialization rules.
• Destructors: Destructors are used to clean up resources when an object is destroyed. This quiz includes 5 MCQs on destructor behaviour and its role in memory management.
• friend Function and Class: Friend functions and classes allow controlled access to private and protected members. This quiz contains 4 MCQs.
• Static Members: Static members belong to the class rather than any object. This quiz contains 6 MCQs based on the scope, initialization, and behaviour of static variables and functions in a class.
• this pointer: The this pointer points to the invoking object within a class. This quiz contains 5 MCQs that evaluates your understanding of its usage, especially in constructors and operator overloading.
• Function Overloading and Default Arguments: Function overloading allows multiple functions with the same name but different parameters, while default arguments simplify function calls. This quiz includes 6 MCQs on practical scenarios involving both.
• Operator Overloading: Operator overloading allows custom implementation of operators for user-defined types. This quiz contains 11 MCQs on overloading syntax and operator functions.
• Inheritance: Inheritance enables a class to derive from another, promoting code reuse. 15 MCQs in this quiz cover types of inheritance, base and derived class relationships, and constructor chaining.
• Virtual Functions: Virtual functions support runtime polymorphism using function overriding. This quiz contains 14 MCQs that tests your knowledge on virtual tables, dynamic dispatch, and abstract classes.
