Ch 5 Set 2 homework problems
1. The cost of operating a small Beverly Hills auto bumper gold-plating
company can be given by this formula:
Cost = Units3 - 7 Units2
where Units stands for the number of bumpers that are
gold-plated each day.
The company wants a program to determine how many bumpers should be
produced each day to minimize operating costs.
Write a program that calculates and prints the cost for 1 unit, 2
units, 3 units, and so on, until a cost is calculated that is greater
than the previous cost.
Write a program that will play the Hi-Lo guessing game. The user
picks a secret number between 1 and 100. The computer tries to guess
the number in less than five turns. When the computer makes a guess, the
user enters a hint; the letter 'H' indicates the computer's guess was
too high, the letter 'L' means the computer guessed too low.
The program should use the hint to revise its guess.
If the user enters the letter 'W' that means the computer guessed
the number correctly and the computer should reply "I won.".
If the computer takes 5 guesses without winning it should
print a message "I lost."

- a thousand-dollar bonus right away followed by a ten
percent salary increase every year.
- a salary increase of one-twelfth of ten percent each month
(and no bonus).
- You should never use a floating point variable to represent
money, but we will make an exception for this assignment.
