Assignment 2: Fran’s Virtual Fruit Stand, Part 2 Due Week 9 and worth 190 points
Use the concepts and scenario from Assignment 1 to help Fran’s Virtual Fruit Stand increase the functionality of its online shopping cart. When a customer checks out, the shopping cart must store the required data pertaining to each item the customer is buying. Your job is to design a program that will prompt the user for the required data and then store it. The required data includes the item name, the price per pound, and the number of pounds of that item being purchased. When complete, your program should include three (3) arrays, two (2) loops, one (1) conditional statement, and one (1) variable.
Using Visual Logic, design a flowchart that is also a fully functional program to add functionality to the online shopping cart. According to your design, the program must: continually accept data regarding the purchase of fruit until the user enters a sentinel value or until five (5) items are entered, whichever comes first. Prompt the user for each item's name (e.g., “dried apples”), the price per pound, and the number of pounds sold in a month. Store the required data in three (3) arrays with corresponding index values (e.g., itemName[0], pricePerPound[0], poundsPurchased[0], etc.). Store up to five (5) values in each array.
The program must allow the user to end data entry by typing a sentinel value, and upon doing so, it should inform the user of the sentinel value entered. If the user does not enter the sentinel, then the data collection ends after five items. After data entry, the program should print an itemized receipt displaying: the item name, price per pound, number of pounds purchased, and subtotal price for each item (calculated as price per pound multiplied by pounds). It should also display the total weight of the entire order, calculated as the sum of all pounds purchased, and the shipping cost based on the total weight at $0.50 per pound. Lastly, the program should display the grand total price including shipping, using the console output.
Paper For Above instruction
The task revolves around enhancing an online shopping cart system for Frans Virtual Fruit Stand by implementing a simple yet effective program that handles multiple items, tracks essential purchase data, and provides a detailed receipt for the customer. This program is designed to use basic programming constructs such as arrays, loops, conditional statements, and variables, which are core to many programming languages, providing a foundation for understanding data management and user interaction within a retail context.
At its core, the program must repeatedly prompt the user to input three data points for each fruit item: the name, price per pound, and the number of pounds purchased. It should store these data points in three
separate arrays, aligning each item by their index. This approach ensures data integrity and simplifies computations during receipt generation. Arrays are ideal here because they provide a structured way to manage multiple related data points, especially when the number of data entries is limited and known, in this case, up to five items.
The process begins with a loop that continues accepting input until either the user enters a predefined sentinel value—indicating they wish to end data entry—or five items have been entered, whichever occurs first. The sentinel value acts as a user-controlled break in data input, allowing consumers to specify when they are finished shopping. When the sentinel is entered, the program must inform the user explicitly which value was used to terminate input. If five items are entered, the input phase stops automatically. This loop structure is fundamental in control flow, enabling the program to handle variable-length user inputs efficiently.
After data collection concludes, the program proceeds to generate an itemized receipt. For each item recorded, it displays the name, price per pound, pounds purchased, and subtotal cost. The subtotal for each item is calculated by multiplying the unit price by the quantity purchased. The total weight of the order is computed as the sum of all pounds purchased across items. The shipping cost is then calculated at a rate of $0.50 per pound, reflecting typical shipping fee calculations based on weight.
The final amount payable is the sum of all item subtotals plus the shipping fee. This grand total provides the customer with a clear summary of their purchase, costs involved, and shipping charges. All output should be formatted neatly and printed on the console, providing an easy-to-read invoice. This exercise exemplifies how simple data structures and control flow can be used to manage user inputs, perform calculations, and produce formatted output essential for retail transactions.
