Question

1. Ask the user to enter a digit between 0 and 9. Have the program print out the digit in words, for example:

Enter a digit between 0 and 9: 4

You entered the number four

Assume that the user will enter only a single digit. The user may accidentally enter a single character, and this should generate an error message

a digit (0-9) or

a special character (anything else)
