Answer to Question #238602 in C# for Phamela

Question

This question follow the ones last posted:

Open and edit your console application to use a List Class instead (called RecipientList). Update the Recipient class to include the following method: public void updateHours(int H) //update the hours left – //If a student has worked H hours in the department, the number of hours should decrease by H //It is also possible that number of hours can be increased The List Class should declare the list as an array of 10 Recipient objects, and should contain the following methods: public void Add(Recipient addNew) //adds a new recipient to the list (if list is full, an error message is displayed public int Count() //returns the number of objects in the list public void Display() //Displays all the recipients in the list public int Find(string Wanted) //returns the position of the wanted element in the list private int LinearSearch(string Wanted)
