Ninety-nine Bottles

Write a program that outputs the lyrics for the song "Ninety-nine Bottles of Beer on the Wall." Your program should print the number of bottles in English, not as a number. For example:

Ninety-nine bottles of beer on the wall,
Ninety-nine bottles of beer,
Take one down, pass it around,
Ninety-eight bottles of beer on the wall.
...
One bottle of beer on the wall,
One bottle of beer,
Take one down, pass it around,
Zero bottles of beer on the wall.

Design your program with a function that takes as an argument an integer between 0 and 99 and returns a string that contains the integer value in English. Your function should not have 100 different if-else statements! Instead, use % or / to extract the tens and ones digits to construct the English string. You may need to test specifically for values such as 0, 10-19, etc.

Vending Machine

You have invented a vending machine capable of deep frying twinkies. Write a program to simulate the vending machine. It costs $3.50 to buy a deep-fried twinkie, and the machine only takes coins in the denominations of a dollar, quarter, dime, or nickel. Write code to simulate a person putting money into the vending machine by repeatedly prompting the user for the next coin to be inserted. Output the total entered so far when each coin is inserted. When $3.50 or more is added, the program should output "Enjoy your deep-fried twinkie" along with any change that should be returned. Use top-down design to determine appropriate functions for the program.
