Project 4 Due: Thursday, July 25, 2002
Total points : 25
Suppose that a gas company bases its charges on consumption according
to the following table:
-
First 70 cubic meters $5.00 minimum cost
-
Next 100 cubic meters 5.0 cents per cubic meter
-
Next 230 cubic meters 2.5 cents per cubic meter
-
Above 400 cubic meters 1.5 cents per cubic meter
Meters readings are four-digit numbers that represent cubic
meters. Write a program in which the meter reading for the previous
month and the current meter reading are entered and then the amount of
the bill is calculated. Note: The current reading may be less than
the previous one; for example, the previous reading may have been
9897, and the current one is 0103. Your output must look like the
sample output shown below.
Sample Output:
Please enter previous and current meter readings:
1000 1500
Cost of gas is 17.25000
Enter 'Q' to quit, any other symbol to continue:
C
Please enter previous and current meter readings:
800 1400
Cost of gas is 18.75000
Enter 'Q' to quit, any other symbol to continue:
Q
Thank you and good-bye
Please email the program to the grader by midnight on the due date.
