C++ OOPs Practice Problems
Last Updated : 10 Apr, 2025
OOPs, stands for Object Oriented Programming, is a technique of writing programs using the real-world concepts such as class, objects, encapsulation, inheritance, abstraction and polymorphism. It is preferred over other techniques as it produce more secure, robust and scalable software. It is one of the most important and used programming paradigms.
Practicing problems is one of the most effective ways to improve your understanding of the concepts. Although OOPs is mostly used in software development, this article list a structured set of practice questions of C++ OOP concepts such as classes, objects, inheritance, polymorphism, etc.
Prerequisite
You should have the knowledge of the following concepts along with OOPs in C++ to solve the above problems:
- Variables and Data Types
- Operators
- Input and Output
- Control Statements and Loops
- Functions
- Compound Data Types
- Dynamic Memory
- C++ OOPs
If you want to revise these topics, refer to the GeeksforGeeks' C++ Tutorial.
How to solve practice problems?
Each of the above link will take you to the practice portal where the problem statement tells you all the required information about the problem, and you have to write the solution in the code editor.
Screenshot of Code EditorOnce your solution is complete, you can check it for example test case using the compile and run button at the bottom right of the page.
Editor ControlsIf you are sure of your solution, press the submit button. The GfG's compiler will run your solution for a variety of test cases and if all these cases are passed, you solution will be accepted.
Your own custom cases can also be checked before submission by using Custom Input button but keep in mind to follow the program's input layout.
