C++ OOPs Quizzes Last Updated : 14 Apr, 2025 Comments Improve Suggest changes Like Article Like Report 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.Quzzes are one of the best and quick way to test your knowledge. This quiz is designed to test your knowledge of important OOPS concepts in C++.C++ OOPs QuizzesThe following list contains topic-wise quizzes from Object-Oriented Programming in C++:OOPs in C++: This quiz contains 25 questions from basic introduction of OOPs.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.How to Answer Quiz?Each of the above topic is linked to the corresponding quiz page that contains 10 or more Multiple Choice Questions (MCQs).
