Write a program in c$++$ that repeatedly requests the user to enter an alphabetic character or a digit from $09.$ Then, print a message identifying the character as a number, a lower case letter, or an uppercase letter. Print an error message if the user enters something other than a digit or alphabetic character. Then, have your program exit.

HINT: You will want to find a website that lists the ASCII characters$$ decimal values. However, the best solutions will not compare a character to a number.

For example, while the following works:

if$($myChar $>97)\{\}$

For readability, the following is preferable:

if$($myChar $>$a$)\{\}$
