Write a program that uses an object of type ServiceRequests to keep track of customers that have called. It should have a loop that, in each iteration, attempts to add a name, remove a name, or print all names. Use an array of size 10 as the list of names.

Suppose that you are in charge of customer service for a certain business. As phone calls come in, the name of the caller is recorded and eventually a service representative return the call and handles the request. Write a class ServiceRequests that keeps track of the names of callers. The class should have the following methods: • addName(name)—adds a name to the list of names. Throws a ServiceBackUpException if there is no free space in the list. • removeName(name)—removes a name from the list. Throws a NoServiceRequestException if the name is not in the list. • getName(i)—returns the ith name in the list. • getNumber—returns the current number of service requests. This project is fairly straightforward. ServiceRequests is really a queue. RemoveName is the only complicated methods in the class. An iterative approach that leaves it for last would be a good idea. The program is a basic while loop with multiple cases for each of the operations of the Service request class.
