Write a program that will calculate and print out bills for the city water company. The water rates vary, depending on whether the bill is for home use, commercial use, or industrial use. A code of h means home use, a code of c means commercial use, and a code of i means industrial use. Any other code should be treated as an error. The water rates are computed as follows: ■ Code h: $5.00 plus $0.0005 per gallon used ■ Code c: $1000.00 for the first 4 million gallons used and $0.00025 for each additional gallon million gallons; $2000.00 of usage is more than 4 million gallons but does not exceed 10 million gallons; and $3000.00 if usage exceeds 10 million gallons Your program should prompt the user to enter an account number (type int), the code (type char), and the gallons of water used (type float). Your program should echo the input data and print the amount due from the user.
