QUESTION 3. This is a compulsory question related to OOP. You are required to provide a mix of descriptive answer and C++ code. A shipping company has a large fleet of Takers and Container ships. You are required to implement a simple program using object-oriented programming techniques that is going to be used to hold the basic information about the vessels of this shipping company. Note that each ship has the following basic information: name, IMO number, port of registration, length, beam, draft, cruising speed, and vessel classification. These two categories of ships use different capacity measurements - container ships use TEU (Twenty-foot equivalent units) while tankers use DWT (Deadweight Tonnage). Answer the following questions: a) What is the meaning of inheritance and polymorphism in the context of OOP? Enhance your answer by making a reference to the above shipping company scenario. Suggest how inheritance and polymorphism techniques can be used to represent the above types of ships. In you answer clearly indicate any super classes and sub classes. (13 marks) b) Implement using C++ the classes mentioned in question (a) above. Your implementation should include the following: i. Use of encapsulation but there is no need to implement any getters and setters. (5 marks) ii. Implementation of constructors that accept as parameters all the attributes of the respective class. (8 marks) iii. Implementation of (override) functions (called displayDetails) that can be used to display the details of the ships. (12 marks) c) Declare an array that can hold three instances of Tankers and/or Container vessels. (5 marks) d) Instantiate three objects and store them in the array that you have declared in question (c) above. The objects should represent a tanker and two container ships with the following information: (1
