Coding Language: C++
1. Modify your Project 1 code to display the number of dollars, quarters, dimes, nickels, and pennies that the customer should receive as change only if the payment amount is greater than the amount owed. Otherwise, display a descriptive error message.
2. Modify your Project 1 code that calculates the cost of the telephone bill. Now customers are charged $10 for the first 50 minutes and $.20 a minute for all minutes over 50. Use named constants for the base cost and the per minute fee.
3. Add a menu to offer the user a choice of processing a telephone bill or translating a phone word to a phone number.
Letters - PhoneNumber Digit
ABC 2
DEF 3
GHI 4
KL 5
MNO 6
PQRS 7
TUV 8
WXYZ 9
4. Validate the user’s menu choice. If the user enters any number other than 1 or 2, a descriptive error message should display. See Sample Output below for format.
5. If the user chooses to translate a phone word, your program (for now) should prompt the user for a single letter and then display the cooresponding phone number digit. If the user’s input can not be translated into a number, then a descriptive error message should display. Your program should translate both upper and lower case letters.
Bonus Pts . After completing all instructions above, add code to validate the user’s input for the phone letter. If the input contains more than one character, then your program should display a descriptive error message. Your program should only translate the user’s input into a numeric digit if it contains exactly one character. You must follow all these instructions to receive full credit.
