Player tells program how many games he/she wants to play.
The player enters six (6) numbers from 1 to 40 at the prompt, one number at a time. The program must catch and report duplicate number entry. It must catch and report invalid entries i.e. numbers outside range of 1 – 40.
The program displays the player’s numbers in sorted order.
The program does an instant random drawing. i.e. creates a set of six (6) winning numbers and displays them in sorted order.
The program compares the computer’s numbers to the player’s numbers and reports the payout.
If the player has additions games to play, repeat steps 3 - 6.
At the end of the player’s session, the program summarizes the player’s transactions. Report Amount wagered, amount won, and net gain. Net gain is the difference between amount won and amount wagered.
