  6. * This program accepts a float value for how many pounds of food each of three
  7. * monkeys eats each day for one week. It stores the data in a two-dimensional 
  8. * array and displays a report containing the average food eaten per day by the 
  9. * monkey family, as well as the least and greatest amounts eaten by any monkey.
  10. * ______________________________________________________________________________
  11. * INPUT
  12. * Food      		// Pounds of food eaten by each monkey each day
  13. * 
  14. * OUTPUT
  15. * Average food  	// Average food eaten per day by the family
  16. * Least food    	// Least food eaten by one monkey in a week
  17. * Greatest food		// Greatest food eaten by one monkey in a week
