Answer to Question #260719 in C# for Phamela

Question

This task is based on your prac 3, where you needed to implement a program for a car salesman who wants to keep record of the cars he has for sale. For each car he keeps the following: Registration Number (always unique), Model, Colour and Price You can carry on with your own solution, and update it to do the following:  Cars should be classified as cheap if the selling price is < R50 000  Make use of the CarPracSkeletonCode file, to implement the methods in CarList related to sorting. Test whether your sorting is valid by calling the public sorting methods from the application class. Alternatively, you can start a new Console application, create the required classes and copy the partial code from the CarPrac SkeletonCode document to the relevant classes  Then implement the methods in Carlist related to sorting. Test whether your sorting is valid by calling the public sorting methods from the application class.
