// File Name: A6russellr.cpp
// Written by: Robert Russell
// Description: Final Project, PowerBall.  Generates 5 random numbers between 1 and 59 and 1 PowerBall between
// 1 and 35.  Asks user to pick same format of numbers and matches based on the rules of the PowerBall lottery
// game.
// Challenges: Generating Random Numbers, Comparing two different sets of numbers with different rules.
// Time Spent: Approx 10 hours
// Given Input: (3 sets)         Expected Output: (3 corresponding sets)
// --------------------          -------------------------
// 1) t , 1 2 3 4 5 6            Your Numbers: 1, 2, 3, 4, 5, PowerBall: 6
//								 PowerBall Numbers: ##, ##, ##, ##, ##, PowerBall: ##
//								 You need to match at least the powerball or three white balls to win.
// Revision History
// Date:        Revised By:     Action:
// ------------------------------------------------------------------
// 4/28			RSR				Wrote inArray, printArray functions
// 4/30         RSR             Added in function definitions, tested random numbers
// 5/4          RSR				Finished.
// 5/6          RSR             Fixed srand, added odds of winning, changed powerball to 1-35, fix modulus statement, fix calling GeneratePowerball() twice
