Practice Perl Programs Set #1
(we'll do these in class)

Work with a partner on these. Show your working program to either Anthony or me when you are done. In all cases, you should write complete perl programs.


1) Calculate tax due with AMT (alternative minimum tax).
Your program should prompt (ask) the user to enter his/her earnings for 2011. It should then calculate and output
the amount of tax to pay. The amount of tax to pay is the larger of 5000.00 or 23% of earnings entered.

2) Shopping coupons for money!
Your program should prompt (ask) the user how many shopping coupons he/she has and output how much money
he/she will receive for redeeming the coupons. Coupons are redeemed according to the following table:

At least	But not more than	Amount
0	999	0.00
1000	5000	23.00
5001	10000	65.00
10001	50000	93.00
50001		156.00 + 0.01 for each coupon over 50001

3) Sort 2 numbers
Ask the user to enter 2 numbers. Your program should output the two numbers in increasing order. Print each number on a seperate line.

4) Sort 2 names(almost the same problem as the previous one)
Ask the user to enter 2 names. Your program should output the two names in alphabetical order. Print each name on a seperate line.
