  4. * ANALYZE BUDGET

  6. * This program accepts a floating point value for the amount budgeted for a 
  7. * Month. A loop then accepts values for every expense for the month. It then
  8. * Evaluates whether the expenses are over or under the budget.
  9. * ______________________________________________________________________________
  10. * INPUT
  11. * Budget	 // Amount set for budget
  12. * Expenses   // Every expense in the month
  13. * 
  14. * OUTPUT
  15. * Difference // The amount that is under or over budget
