Here are some great things to think about as you begin your program!
Define a function named ReadDials() that reads each digit and letter
dialed into 8 separate char variables (DO NOT USE ARRAYS). All the
digits are sent back through parameters by reference.
Then, for each digit, the program will use a function named ToDigit(),
which receives a single char argument (pass by reference) that may be a
number or a letter of one of the digits dialed.
If it is a number, then return 0 by value indicating that it is a valid digit.
If the digit is a letter, then the number corresponding to the letter is
returned by reference, and return 0 by value indicating that it is a valid
digit. Here are the letters associated with each digit.
