//
// Program Description and Design Overview:
// // -------------------------------------------------------------
// Program FatCalories calculates a person's percentage of 
// calories obtained from fat and prints an appropriate message.
// -------------------------------------------------------------


// The American Heart Assn. recommends that no more than 30 percent
// of a person's daily calories come from fat.  Each gram of fat is 9 calories.
// Given the grams of fat and the number of calories in a food item, we can
// calculate the percentage of calories that comes from fat for that food item.

// Program design:
// 1. Prompt user to enter name of a food
//    "Enter the name of a food item: "
// 2. Input food name
//    Hint: The food name may be more than one word.  This variable should be a
//          String.  Use Keyboard.readString() to input all the words typed
//          on a line (including the whitespace between them) into one String
//          variable.  (If you just wanted to read the next single word typed
//          on a line, you should use Keyboard.readWord())
// 3. Prompt user to enter the grams of fat in the food
//    (for the food he/she entered in previous input)
//    "Enter the grams of fat: "
// 4. Input grams of fat
// 5. Prompt user to enter the number of calories in the food
//    "Enter the the number of calories: "
// 6. Input the number of calories
// 7. Print the food item and the percentage of calories that come from fat
//    (fatCalPercent)
// 8. Print one of the two following messages depending on the percentage
//    of calories from fat (value of fatCalPercent).
//   "This item is Heart Heathy!"
//   "This item is NOT Heart Heathy!"
//   (Note, there are at least four different ways to code this in Java.)
//
//
// Run your program 4 times with the following data:
//  Item    Grams of fat    Calories
// -------- ------------    --------
// Tuna           1            60
// Spaetzle       2           170
// V8 Juice       0            35
// Corned Beef    7           200
//
// Write down your answers.  When done edit your Java source file and insert the
// food item name, the percentage of calories from fat (value of fatCalPercent),
// and whether that food is Heart Heathy or NOT Heart Heathy for each of the
// 4 items as comments in your program.
//
//
// Input Requirements:
//      
//
// Output Requirements:
//      
//      
//
// Program Preconditions:
//
