Description: 1) Write a C++ program that receives a single letter and prints out the corresponding digit on the telephone. The letters and digits on a telephone are grouped this way: (30 points)
2= ABC 3 = DEF 4 = GHI 5 = JKL
6 = MNO 7 = PRS 8 = TUV 9 = WXY
No digit corresponds to either Q or Z. For these 2 letters your program should print a message indicating that they are not used on a telephone.
The program may operate like this:
Enter a single letter and you will get the corresponding digit on the telephone: R
The digit 7 corresponds to the letter R on the telephone
Another example:
Enter a single letter and you will get the corresponding digit on the telephone: Z
There is no digit on the telephone that corresponds to Z
NOTE: Your program should accept only uppercase letters (appropriate error message for special characters or lowercase letters)
Also write a loop that lets user to insert his/her letters, until the character (“$”) is entered.
