The document is a comprehensive question bank on Object-Oriented Programming (OOP) prepared by professors Shailesh Kulkarni and Nitin Bhopale at Sanjivani College of Engineering. It contains a wide range of questions covering various topics such as applications of C++, benefits of OOP, inheritance, polymorphism, exceptions in Java, constructors, destructors, and many programming tasks. Students are expected to prepare programs based on the questions listed and understand fundamental concepts in OOP.
