  5. * SIMULATE COIN COUNTING GAME
  6. * ____________________________________________________________
  7. * This program simulates a coin counting game where the defined quantities of 
  8. * coins including pennies, nickels, dimes, and quarters must equal a specific 
  9. * dollar amount.
  10. *
  11. * The simulation is based on the following analysis:
  12. * If the value of each coin multiplied by the quantity of each coin is equal to 
  13. * the specified dollar amount, the player wins the game.
  14. * ____________________________________________________________
  15. *INPUT
  16. * pennyQuantity : Player's quantity of pennies
  17. * nickelQuantity : Player's quantity of nickels
  18. * dimeQuantity : Player's quantity of dimes
  19. * quarterQuantity : Player's quantity of quarters
  20. * pennyValue : Monetary value held by one penny
  21. * nickelValue : Monetary value held by one nickel
  22. * dimeValue : Monetary value held by one dime
  23. * quarterValue : Monetary value held by one quarter
  24. * dollarGoal : Goal dollar amount to be counted
  25. *
  26. *OUTPUT
  27. * coinTotal : Total value of all coins entered
