The digit 7 corresponds to the letter R on the telephone.

The program should display a message indicating that there is no matching digit for any non- alphabetic character entered by the user.

Question 4. Generate test cases as part of a test plan to exercise all branches of your program. Use the Test Plan document to list all of your test data and the expected results. You do not need to test every letter, however you do need to use input data that will test each branch of the selection statements; for example, the letter R tests option 7, so you do not need to test letters P, Q, or 5.
