Given the class hierarchy involving vehicles, including classes for car, truck, minivan, and SUV, the task involves completing constructors for the derived classes, testing object creation and display methods, and implementing polymorphism via virtual functions. The goal is to demonstrate inheritance, constructor initialization, method overriding, and polymorphic behavior in C#.

Paper For Above instruction

The objective of this assignment is to deepen understanding of inheritance, constructors, method overriding, and polymorphism in object-oriented programming using C#. The assignment requires completing class constructors, creating objects, and utilizing virtual methods to achieve runtime polymorphism.

Initially, students are provided with a base class vehicle that encapsulates common attributes such as make, model, year, wheels, and weight. The class has two constructors: a default constructor initializing default values and a parameterized constructor for setting specific values. The DisplayVehicle method outputs vehicle details and is marked virtual to allow overriding.

Derived classes car and truck extend vehicle and add specific attributes like passenger capacity, payload capacity, and their own display methods such as DisplayVehicleCar and DisplayVehicleTruck. The task involves implementing constructors for these classes that initialize both inherited and unique members, and modifying display methods to override the base method.

Further, students expand their hierarchy by adding minivan and SUV classes, also derived from vehicle. These classes require similar constructors and display methods, which should override the virtual method from vehicle. The main function tests object creation, displaying their information, and demonstrates polymorphism by creating an array of vehicle objects, populating it with different types, and displaying each vehicle's details via a loop. This emphasizes runtime behavior where the correct DisplayVehicle method executes based on actual object type.

Implementing this structure fosters mastery in C# inheritance syntax, constructor chaining, method overriding with the override keyword, and polymorphism using base class references pointing to derived class objects. Proper organization and testing of class constructors ensure robust object initialization, while polymorphic display methods reinforce dynamic method dispatch concepts essential in advanced object-oriented programming.
