Object Oriented System Design with C++ Unit 5 – Objects Classes Inheritance and Polymorphism: important questions for AKTU
Unit 5 (Objects Classes Inheritance and Polymorphism) questions that AKTU repeats most often. This unit carries about 38 marks per paper. Start with the repeated questions, then the most asked topics.
Most repeated Unit 5 questions
- What is pointer in C++ ? Write a C++ program to demonstrate the use of this pointer. Write a program to illustrate constructors and destructors. (7 marks, 2026, Polymorphism) – also asked in 2021, 2022, 2023, 2024, 2025
- Discuss operator overloading and type conversion in C++. Explain different types of inheritance with diagrams and examples. (7 marks, 2026, Inheritance) – also asked in 2021, 2022, 2023, 2024, 2025
