Question: what is oop? | ||
Student Answer: OOP is object oriented programming.It is composed of classes and objects. It has functions like encapsulation, inheritance, polymorphism and so on. It is used by languages like C++, java, python, etc. It is considered more efficient than procedural oriented programming as it can be reused further and provides answer faster. | ||
Score: { | ||
"marks": 4, | ||
"comment": "Your answer provides a basic understanding of OOP and its advantages, but it lacks depth and explanation of the concept of objects and classes. Try to focus more on programming principles and look for mention of objects and classes to understand the topic better." | ||

Question: What is a data structure? | ||
Student Answer: A data structure is a method for efficiently organizing and storing data. It involves defining relationships between data elements and specifying operations that can be performed on the data. It is also used for processing, retrieving, and storing data. There are different basic and advanced types of data structures that are used in almost every program or software system that has been developed. | ||
