A contact book is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Your contact book stores names and phone numbers. Write a program that uses the given dictionary and updates the phone numbers in it. Your program is only expected to update the area codes of phone numbers. Your program should first display all contacts by name and number. Then prompt for the current area code, followed by a prompt for the new area code as shown below. Your prompts should end with a newline so that each input is on its own line. Update the contact book by replacing the current area code with the new area code. You will then display all contacts by name and number that are in the updated contact book. If there were no updates, display that message instead of the contact book. Note that you will not be building on your code from program C. This is a new program with a different goal. Examples of the program:

Current Contact Book Joe: IInda: Frank: Enter the current area code: 615 Enter the new area code: 517 Updated Contact Book Joe: Iinda: Frank: Current Contact Book Joe: Linda: Erank: Enter the current area code: 770 Enter the new area code: 615 There were no changes to the contact book.
