Using Visual Logic Design A Flowchart That Is Also a Fully Functional

Using Visual Logic, design a flowchart that is also a fully functional program. According to your design, the program must: Continually accept data regarding the purchase of fruit until a sentinel value is entered. Prompt the user for each item, and accept the name of the fruit (e.g., “dried apples”), the price per pound, and the number of pounds sold in a month. Display a clear message for items that are considered: Best-selling items—those that sell 5,000 or more pounds per month on average; Big-ticket items—best-selling items that also cost $4 per pound or more; High-priced items—items that sell for $7 per pound or more; Lowest-selling items—those that sell 500 pounds or less per month on average; High-income generating items (criteria for this are to be clarified and implemented).

Using Visual Logic Design A Flowchart That Is Also a Fully Functional

The task at hand involves designing a flowchart that is not only a visual representation of a process but also a fully executable program. The program focuses on processing fruit purchase data and categorizing each item based on specific sales and price criteria. This kind of dual-purpose design requires careful planning of the logic flow and translating it into code that can be implemented in a programming language such as Python, Java, or C++.

The core functionality involves repeatedly prompting the user to enter information about fruit items until a sentinel value indicates the end of input. For each fruit entry, the program must accept the fruit name, the price per pound, and the pounds sold in a month. Using this data, the program will determine and display whether the item falls into specific categories:

  • Best-selling items: Sell 5,000 or more pounds per month.
  • Big-ticket items: Are both best-selling and priced $4 or more per pound.
  • High-priced items: Sell for $7 or more per pound.
  • Lowest-selling items: Sell 500 pounds or less per month.
  • High-income generating items: (Criteria need clarification, but could relate to revenue—calculated as price per pound multiplied by pounds sold per month—and determining which items generate the highest income.)

The program continues to accept input until the user enters a sentinel value for the fruit name, such as "done" or "exit". It then processes each item, categorizes it based on the criteria, and displays appropriate messages.

Design Overview

The flowchart begins with the start node, then prompts the user to enter the fruit name. If the input matches the sentinel value, the program terminates. Otherwise, it proceeds to ask for the price per pound and the pounds sold per month. It then evaluates the item's categories based on the input data:

  1. Check if the item is best-selling (pounds >= 5000).
  2. Check if the item is a big-ticket (best-selling and price >= 4).
  3. Check if the item is high-priced (price >= 7).
  4. Check if the item is lowest-selling (pounds
  5. Calculate income (price * pounds) and determine if it is a high-income generating item (e.g., income exceeds a certain threshold). The threshold can be set, for example, at $35,000 or based on the top earning items.

The program then displays the relevant messages for each category, clears the input, and loops back to prompt for the next fruit item. This process repeats until the sentinel value is entered, at which point the program ends.

Implementation in Pseudocode

Start


Loop


Prompt "Enter fruit name (or 'done' to finish):"


Read fruitName


If fruitName equals 'done' Then


Exit loop


End If


Prompt "Enter price per pound:"


Read pricePerPound


Prompt "Enter pounds sold in month:"


Read poundsSold


// Determine categories


If poundsSold >= 5000 Then


Display " is a best-selling item."


End If


If poundsSold >= 5000 And pricePerPound >= 4 Then


Display " is a big-ticket item."


End If


If pricePerPound >= 7 Then


Display " is a high-priced item."


End If


If poundsSold 

Display " is a lowest-selling item."


End If


income = pricePerPound * poundsSold


// Assuming threshold for high-income is $35,000


If income >= 35000 Then


Display " is a high-income generating item."


End If


End Loop


End

Sample Output

Enter fruit name (or 'done' to finish): dried apples

Enter price per pound: 3.50

Enter pounds sold in month: 6000

dried apples is a best-selling item.

dried apples is a big-ticket item.

dried apples is a high-priced item.

Enter fruit name (or 'done' to finish): dried Ugli Fruit

Enter price per pound: 2.00

Enter pounds sold in month: 400

dried Ugli Fruit is a lowest-selling item.

Enter fruit name (or 'done' to finish): frozen blueberries

Enter price per pound: 5.00

Enter pounds sold in month: 300

frozen blueberries is a high-priced item.

The design ensures that each fruit entry is analyzed and categorized appropriately, providing valuable insights into sales trends and profitability.

Conclusion

This program combines logical decision-making with user interaction to classify fruit items effectively. The flowchart guiding this process can be translated into a visual representation that maps out each decision point and flow of control, making it a useful tool for both understanding and implementing the logic in software development.
