Create an object-oriented program that works as a personal, editable telephone directory. It will operate through the interaction of two objects: Interface and Directory.

The Interface object will interact with the user, taking requests, and sending information to the Directory object, where the data is actually stored.

The methods of the Interface object should be:

• searchByLastName(string lastName)
• searchByNumber(int number)
• addEntry(string lastName, string firstName, int number)

The methods of the Directory object should be:

• returnName(int number)
• returnNumbers(string last Name)
• updateList(string lastName, string firstName, int number)

The Directory object should also contain three arrays of size 10, in which the indexes correspond; that is number[0] should be the phone number for lastName[0] and firstName[0]. When your program begins, you should have at least 4 numbers and names already present, so that you can test the search functions.
