Purpose: print a table of items and prices for half and full day rentals.
prompt the user to pick from 1,2,3 corisding to the equip items and H/F for
half or full day rental. use a switch statment to pick items from list.
use a do while loop based on a Y/N user entry.
there is error checking, program works for only vaild entries.
every thing that needs to be commented is, every thing else is strait forward
