1. Write a program that takes user-entered lines and stores them in an array. When the user enters "quit", the program prints out all the lines. Call it "prog2_1.pl".

2. Modify program 1 so that it prints out the lines in reverse order. Call it "prog2_2.pl".

3. Modify program 1 so it first sorts the lines (ASCII order), then prints them out. Call it "prog2_3.pl".

4. Modify the program so it tells you how many lines have been entered, and then prints out only lines 2, 3, and 4. Call it "prog2_4.pl".

5. Write a program that adds up all the numbers between 1 and 50, and also adds up the squares of those numbers. Have it print out the results. prog2_5.pl.
