3 Write a program that calculates the number of gallons, quarts, pints and cups in a 42 liter gas tank. Use modulus, integer divide operations and type coercion. 1 gallon = 4 quarts = 8 pints = 16 cups = 3.78541 liters. Only the smallest value should have decimal places, all the other values should be integers. Find out the total amount of cups, then from that go up to gallons. Use type coercion, save the decimal part, and work with the integer part. At the end, recover the decimal part into the smallest unit. In C++ please
