Phone Program

[jayman]

I have a program i am trying to build and i kinda lost on what to do. Any help or advice will be great. Here is the pseudo code i am using.

Using the pseudo code below, write the code that will meet the requirements:
Main Function
Declare the char variables for the 8 digits of the phone number
while true
Call the ReadDials function passing the 8 digits
by reference. ReadDials returns an error code by
value.
If the return value is -5, exit the do while loop
If the error code is -1, display the
error message "ERROR - An invalid character was entered".
If the error code is -2, display the
error message "ERROR - Phone number cannot begin with 0".
If the error code is -3, display the
error message "ERROR - Phone number cannot begin with 555".
If the error code is -4, display the
error message "ERROR - Hyphen is not in the correct position".
Otherwise, call the AcknowledgeCall function
End-While
ReadDials function
Input the first digit
If a Q was entered, return -5.
Input the rest of the phone number
Call the ToDigit function for each of the 7 digits
not for digit 4
If ToDigit returns -1, return -1
If digit 4 is not a hyphen, return -4.
If digit 1 is 0, return -2.
If digits 1 - 3 are 5, return -3
Otherwise, return 0
ToDigit function
Convert the digit to upper case
Use a switch statement to determine if the digit is valid
and convert the letters to digits
If the digit is invalid, return -1.
If the digit is valid, return 0.
AcknowledgeCall function
Display the Phone Number.

Here is a link to my code so far.
