  7. *
  8. * 
  9. * Computation is based on the Formula:
  10. *	If the result is positive → you are under budget
  11. *	If the result is negative → you are over budget
  12. *	If the result is zero → you are exactly on budget
  13. *______________________________________________________________________________
  14. * INPUT
  15. *	Budget		: (one value)
  16. *	Expenses	: (multiple values)
  17. *	Continue choice : (y or n)
  18. * 
  19. * OUTPUT
  20. *	Over budget message		: user has spent more than the budget
  21. *	Under budget message	: user has spent less than the budget
  22. *	On budget message		: user spent exactly the budgeted amount
