Answer to Question #59290 in C++ for Fady.s

Question

Keeping track of and converting between US fluid quantities can be quite confusing and challenging, given all those tablespoons, ounces, quarts, etc. The relationships between all of these fluid units are:

1 fluid ounce = 2 tablespoons
1 gill = 4 fluid ounces (fl oz)
1 cup = 2 gills
1 pint = 2 cups
1 quart = 2 pints
1 gallon = 4 quarts
1 barrel = 42 gallons

Write a program that asks the user to input a number of fluid ounces. Allocate the fluid ounces into the various units, first starting with barrels, then gallons, and so on, finishing with tablespoons.

Sample 1:
How many fluid ounces do you have? 77
77 fluid ounces can be divided into:
0 barrel(s)
0 gallon(s)
2 quart(s)
0 pint(s)
1 cup(s)
1 gill(s)
2 tablespoons

Sample 2:
How many fluid ounces do you have? 6555
6555 fluid ounces can be divided into:
1 barrel(s)
9 gallon(s)
0 quart(s)
1 pint(s)
1 cup(s)
0 gill(s)
6 tablespoons
