  5. * Caculate Stadium Seating Income
  6. *-------------------------------------------------------------------------------
  7. * This program asks how many tickets for each class of seats were sold, then 
  8. * displays the amount of income generated from ticket sales.
  9. *
  10. * computation is based on the formula:
  11. * Total = Numb1 x Unit price of ClassA+ Numb2 x Unit price of ClassB+Numb3 x Unit price of ClassC
  12. *-------------------------------------------------------------------------------
  13. * INPUT
  14. *    numb1      : The amount of solded class A seats
  15. *    numb2      : The amount of solded class B seats
  16. *    numb3      : The amount of solded class C seats
  17. *    unitPriceA : The unit price of class A seats.
  18. *    unitPriceB : The unit price of class B seats.
  19. *    unitPriceC : The unit price of class c seats.
  20. * OUTPUT
  21. *    total      : The amount of income generated from ticket sales
