Project #2

## Language Should be Python. Using for, while, if, elif only. No advanced functions.

Assignment Specifications

The program will compute and display information for a company which rents vehicles to its customers. For a specified customer, the program will compute and display the amount of money charged for that customer’s vehicle rental.

1. The program should start by asking the user if he wants to continue. The answer is ‘Y’ for yes or ‘N’ for no.

The basic structure of the main loop is

Prompt to see if the user wants to continue

While the value is ‘Y’:

All your other code goes here

Prompt to see if the user wants to continue

2. It will then continue to prompt the user to enter the following four items for a given customer (in the specified order):
3. 1. The customer's classification code (a character)
4. 2. The number of days the vehicle was rented (an integer)
5. 3. The vehicle's odometer reading at the start of the rental period (an integer)
6. 4. The vehicle's odometer reading at the end of the rental period (an integer)

It will then process that customer information and display the results. At the end, the program should ask the user if he wants to process another request and it will keep asking until the user enter 0.

3. The program will compute the amount of money that the customer will be billed, based on the customer's classification code, number of days in the rental period, and number of miles driven. The program will recognize both upper case and lower case letters for the classification codes.

Code 'B' (budget)

base charge: $40.00 for each day

mileage charge: $0.25 for each mile driven

Code 'D' (daily)

base charge: $60.00 for each day

mileage charge: no charge if the average number of miles driven per day is 100 miles or less; otherwise, $0.25 for each mile driven above the 100 mile per day limit.

Code 'W' (weekly)

base charge: $190.00 for each week (or fraction of a week)

mileage charge: no charge if the average number of miles driven per week is 900 miles or less; $100.00 per week if the average number of miles driven per week exceeds 900 miles but does not exceed 1500 miles; otherwise, $200.00 per week plus $0.25 for each mile driven above the 1500 mile per week limit.

The amount billed to the customer is the sum of the base charge and the mileage charge.

4. The program will compute the number of miles driven by the customer during the rental period. The odometer readings are taken from an odometer which has six digits and records tenths of a mile.
5. For each customer, the program will display a summary with the following information:
6. 1. The customer's classification code
7. 2. The number of days the vehicle was rented
8. 3. The vehicle's odometer reading at the start of the rental period
9. 4. The vehicle's odometer reading at the end of the rental period
10. 5. The number of miles driven during the rental period
11. 6. The amount of money billed to the customer for the rental period

All output will be appropriately labeled and formatted. The number of miles driven will be rounded to one fractional digit. The amount of money billed will be displayed with a dollar sign and will be rounded to two fractional digits (for example, $125.99 or $43.87). Note that we do not have the ability yet to fine tune the output so if cents end in zero that final zero will not be

displayed—that is fine for this project. We provide a file strings.txt with the strings we used to make it easier for you to match our output.

6. The program will detect, report and recover from invalid classification codes. When an invalid classification code is detected, the program will display an error message and re-prompt until a correct classification code is entered.

Hint: use a while loop that will loop until a correct classification code is entered. Here is pseudo code of that loop:

Prompt for a value

While the value is not correct:

Print an error message

Prompt for a value

7. The program will assume that all other user inputs are valid and correct. That is, the program will not check the number of days or odometer readings for validity. However, as noted below you may encounter an ending odometer reading that is less than the beginning reading and you need to handle that correctly.

Assignment Notes

1. As stated above, the odometer's dial has six digits and records tenths of a mile. For example, if the beginning reading was 100003 and the ending reading was 100135, then the customer drove 13.2 miles during the rental period.
2. Since the odometer’s dial is fixed with only six digits, the reading at the end of the rental period may be less than the reading at the beginning of the billing period. For example, if the beginning reading was 999997 and the ending reading was 000005, then the customer drove 0.8 miles during the rental period. You need to handle that arithmetic correctly.
