Review the customer requirements and IPO found below: The customer needs to determine what the shipping costs will be for a package. The shipping cost is determined by weight. Once the weight is entered the program should display the rate used and the total shipping charges. Weight of Package Rate per Pound 2 lbs or less 1.00 Over 2 but not more than 6 lbs 2.25 Over 6 but not more than 10 lbs 3.50 Over 10 lbs 4.10

· personal message (i.e., not just the fee). · Display a message for end of program and programmer credits · Display a message with customer information (customer name and account number)

- Open Flowgorithm and save with the required naming conventions in the “Lab Task Checklist” and remember to enter your Program Attributes.
- Create the
algorithm using Flowgorithm to meet the customer requirements.- Display a welcome message and the purpose of the program
- Reserve Memory Locations (Declare) - Use as short and meaningful names
- Variables - Declare variables close to where they will be used
- Use the correct naming conventions (found in ROE)
- Named constants - Declare named constants at the start of the program
- Use the correct naming conventions (found in ROE)
- Use named constants for each of the different rates. Once rate is determined set the rate to that value. Example: rate = RATE1
- Make sure you are using the correct data type
- Variables - Declare variables close to where they will be used
- Add Decision Structures as needed to meet customer requirements.
- Use prompts to describe required input before asking for input
- The output must clearly delineate what each value is.
- Display end of program message with programmer’s name
- Document your test cases using the comment block of flowgorithm
SPECIAL NOTE:
Do not use magic numbers when named constants are a better choice. i.e., #cost of tickets, TAX rate, fee charges, test for fee. Make sure your calculation uses the NAMED CONSTANTS instead of actual numbers.

Constants: Rates for: · More than 10 · More than 6 less than 10 · More than 2, less than 6 · Equal or Less than 2 Variables: Package weight

Get package weight Assign each rate for shipping
Test for rate to be charged Set rate to rate to be charged (hint: your constants)
Calculate shipping total · Shipping total = rate * weight **hint: The order that you test matters. |
Welcome message Prompt: weight
Result: Rate charged and total shipping cost
