OOP Concept introduces Object-Oriented Programming and its approach to organizing programs around objects and classes. Students learn about classes, objects, encapsulation, inheritance, polymorphism and abstraction. The chapter also compares object-oriented programming with procedural programming and explains the advantages of the OOP approach.

This page covers OOP Concept, chapter 5 of 7 in the Class 12 Computer Science syllabus set by the National Examination Board (NEB). 11 important questions for this chapter are available, each with a full solution.

For numerical and derivation-based chapters like this one, working through past NEB questions is usually more useful than re-reading notes alone — try solving each important question above before checking the solution, then compare your working step by step.
