  5.  * Displaying Meal Cost, Tax Amount, Tip Amount, and Total Bill for a Meal
  6.  * 
  7.  * _____________________________________________________________________________
  8.  * This program computes and displays the tax and tip amount of a restaurant 
  9.  * bill for a $44.50 meal charge based on the meal cost, tax percentage, and tip 
  10.  * percentage after tax. It will also display the total bill.
  11.  * 
  12.  * Computation is based on the formula:
  13.  * taxAmount = mealCost * taxPercent
  14.  * tipAmount = (mealCost + taxAmount) * tipPercent
  15.  * totalBill = taxAmount + tipAmount + mealCost
  16.  * 
  17.  * _____________________________________________________________________________
  18.  * INPUT
  19.  * mealCost = initial charge of meal ($44.50)
  20.  * taxPercent = sales tax (6.75%)
  21.  * tipPercent = tip percent based on charge after tax (15%)
  22.  * 
  23.  * OUTPUT
  24.  * taxAmount = charge of tax 
  25.  * tipAmount = charge of tip after tax 
  26.  * totalBill = computes total charge of meal
