// Contract: main: void -> int
//
// Purpose: ask user for the beginning ticket price and the
//          ending ticket price, and then print to the
//          screen the profits for each ticket price
//          in that range, inclusive --- [beginning, ending] ---
//          in dime increments.
//
// Examples: If the user enters a beginning price of $4 and an ending
//           price of $4.3, the following would be printed to the screen:
//
// Profits for ticket prices between $4 and $4.3 (in dime increments)
// --------------------------------------------------------------
// ticket_price   profit
// ------------   ------
// $4              $889.2
// $4.1            $855.3
// $4.2            $818.4
// $4.3            $778.5
