These are the questions I have to do on my assignment:

1) Write, test, and debug (if necessary) a Ruby program with the following specification:

Input: Three numbers, a, b, and c, each on its own line, from the keyboard.

Output: The value of the expression 10ab-((c-1)/17.44).

-------------------------------------------------------------------------------

2) Write, test, and debug (if necessary) a Ruby program with the following specification:

Input: Three names, on separate lines, from the keyboard.

Output: The input names in alphabetical order. Do not use arrays.

--------------------------------------------------------------------------------------

3) Write, test, and debug (if necessary) a Ruby program with the following specification:

Input: A list of numbers from the keyboard.

Output: Two lists of numbers, one with input numbers greater than zero and one with those less than zero (ignore the zero-valued numbers). You must first build two arrays with the required output numbers before you display any of them.
