Class

Object Oriented Programming System (OOPs) is a programming model built on the perception of “objects” that contains data and methods. The major purpose of Object Oriented Programming is to increase the maintainability and flexibility of programs. Object Oriented Programming gets together data and its behavior (methods) in a single location (object) which makes it easier to understand.

Please I need to answers these questions in C++. Thank you. Question: Does the if-else if structure offer any advantages over nested if statements? Choose the correct answer from below: A. It helps keep the code understandable and readable on the screen or on paper B. It does away with the need of a trailing else C. It can handle logic that nested if statements cannot handle D. Neither has an advantage over the other E. The text did not discuss this topic Question: What is the purpose of a trailing else in an if-else if ladder structure? Choose the correct answer from below: A. It handles the "none of the above" situation in the problem B. Two of the other answers are correct C. It is often used to catch errors D. It deals with the most complex boolean expression E. It is the only part of the ladder that is not optional
