Part Of The New System Design Is A Software Program That Will Allow Us

Part of the new system design is a software program that will allow users to work out the cost of the Explorer Pass. Write an algorithm in pseudocode for a Calculate Charge module that will: • allow the user to enter the number of family, adult and child passes required • allow the user to enter the number of tours the pass will be valid for • display the cost of each type of pass, the total cost and the amount of GST included (to calculate the amount of GST included, you will need to divide the Total Cost by 11 e.g. if total cost is $169.00, GST included = 169/11 = 15.36). • include error checking to ensure that a valid number of tours are entered and that a valid pass type is selected. Explorer Pass Adult Child Family 1 tour $ 46.00 $23.00 $115.00 2 tours $ 85.00 $42.00 $210.00 3 tours $120.00 $60.00 $320.00 4 tours $150.00 $80.00 $400.00 5 tours $175.00 $95.00 $480.00 Child = 4 to 13 years Family Pass = 2 adults and 2 children A family with 3 children would need to purchase 1 Family Pass and 1 Child Pass

Paper For Above instruction

To develop a comprehensive Calculate Charge module for the Explorer Pass system, the algorithm must facilitate user input, perform validation, calculate costs accurately, and display the results clearly. This process involves several key steps, including input collection, validation, calculation, and output presentation, ensuring a user-friendly experience and precise billing.

First, the algorithm should prompt users to input the number of passes they wish to purchase, specifying quantities for adults, children, and families. Given that a family pass includes two adults and two children, the system should clarify whether the user intends to purchase individual passes or a family pass, or both. It must also prompt for the number of tours the passes are valid for, ensuring the input aligns with available options (1 to 5 tours). Error checking at this stage is essential to ensure that only valid numbers, such as integers within the specified range, are accepted.

The next step involves input validation. The algorithm should verify that the number of tours entered is between 1 and 5. If an invalid number is entered, the system must prompt the user to re-enter a valid value. Similarly, it should confirm that the pass quantities are non-negative integers. If invalid data is detected, the user should be notified and prompted to correct the input.

Once validated, the program proceeds to calculate individual costs based on the number of passes and the number of tours. Using the provided pricing table, the system multiplies the number of each pass type by the corresponding price for the specified number of tours:

  • Adult pass cost = number of adult passes × price per adult pass for chosen tours
  • Child pass cost = number of child passes × price per child pass for chosen tours
  • Family pass cost = number of family passes × price per family pass for chosen tours

The total cost is then derived by summing these individual costs. To include GST, the program divides the total amount by 11, as specified, to find the GST portion included in the total. This calculation is crucial for transparency and accurate billing.

Finally, the system displays a detailed breakdown:

  • Cost of each pass type
  • Total cost of all passes
  • The amount of GST included in the total cost

This ensures that users are fully informed of what they are paying and the breakdown of charges.

Additionally, the algorithm should allow multiple calculations within a session, enabling users to modify inputs and recalculate as needed. The process concludes once the user confirms they have obtained the necessary information.

In summary, the pseudocode algorithm incorporates robust input validation, precise cost calculations based on a tiered pricing structure, and clear output presentation, aligning with best practices for user experience and billing accuracy.

Solution

The pseudocode for the Calculate Charge module begins with user prompts for input, includes validation routines, performs cost calculations, and concludes with displaying a detailed invoice. The steps are as follows:

START


DISPLAY "Welcome to the Explorer Pass Cost Calculator"


REPEAT


PROMPT "Enter the number of adult passes:"


READ numAdults


IF numAdults 

DISPLAY "Invalid input. Please enter a non-negative integer."


CONTINUE


ENDIF


UNTIL valid


REPEAT


PROMPT "Enter the number of child passes:"


READ numChildren


IF numChildren 

DISPLAY "Invalid input. Please enter a non-negative integer."


CONTINUE


ENDIF


UNTIL valid


REPEAT


PROMPT "Enter the number of family passes:"


READ numFamily


IF numFamily 

DISPLAY "Invalid input. Please enter a non-negative integer."


CONTINUE


ENDIF


UNTIL valid


REPEAT


PROMPT "Enter the number of tours (1-5):"


READ numTours


IF numTours  5 OR NOT integer THEN


DISPLAY "Invalid input. Please enter a number between 1 and 5."


CONTINUE


ENDIF


UNTIL valid


SET adultPrices = [46.00, 85.00, 120.00, 150.00, 175.00]


SET childPrices = [23.00, 42.00, 60.00, 80.00, 95.00]


SET familyPrices = [115.00, 210.00, 320.00, 400.00, 480.00]


CALCULATE pass costs


adultCost = numAdults * adultPrices[numTours - 1]


childCost = numChildren * childPrices[numTours - 1]


familyCost = numFamily * familyPrices[numTours - 1]


CALCULATE totalCost


totalCost = adultCost + childCost + familyCost


CALCULATE gstIncluded


gstIncluded = totalCost / 11


DISPLAY "Cost of Adult Passes:", adultCost


DISPLAY "Cost of Child Passes:", childCost


DISPLAY "Cost of Family Passes:", familyCost


DISPLAY "Total Cost:", totalCost


DISPLAY "GST Included:", gstIncluded


ASK "Would you like to perform another calculation? (yes/no)"


IF response = "yes" THEN


REPEAT process


ELSE


DISPLAY "Thank you for using the Explorer Pass Cost Calculator"


END


END

This pseudocode captures the essential logic required for the Explore Pass calculation module. It ensures user inputs are validated, calculations are based on tiered pricing and number of tours, and all costs including GST are transparently presented.
