Step 1: C# sharp Code: using System; using System.Collections.Generic; using System.IO; public class Warehouse { public string Name { get; set; } public Dictionary Items { get; set; } public Warehouse(string name, int[] initialQuantities) { Name = name; Items = new Dictionary { { 102, initialQuantities[0] }, { 215, initialQuantities[1] }, { 410, initialQuantities[2] }, { 525, initialQuantities[3] }, { 711, initialQuantities[4] } }; } public void ProcessTransaction(char type, int itemNumber, int quantity) { if (type == 'S') // Sale { if (Items[itemNumber] >= quantity) { Items[itemNumber] -= quantity; } else { Console.WriteLine($"Error: Sale transaction exceeds available stock at {Name} for item {itemNumber}."); } } else if (type == 'P') // Purchase { Items[itemNumber] += quantity; } } } public class Program { public static void Main(string[] args) { string inventoryFilePath = "Inventory.txt"; string transactionsFilePath = "Transactions.txt"; if (!File.Exists(inventoryFilePath)) { Console.WriteLine($"Error: {inventoryFilePath} not found."); return; } if (!File.Exists(transactionsFilePath)) { Console.WriteLine($"Error: {transactionsFilePath} not found."); return; } // Read and parse Inventory.txt string[] inventoryLines = File.ReadAllLines(inventoryFilePath); List warehouses = new List { new Warehouse("Atlanta", ParseInventoryLine(inventoryLines[0])), new Warehouse("Baltimore", ParseInventoryLine(inventoryLines[1])), new Warehouse("Chicago", ParseInventoryLine(inventoryLines[2])), new Warehouse("Denver", ParseInventoryLine(inventoryLines[3])), new Warehouse("Ely", ParseInventoryLine(inventoryLines[4])), new Warehouse("Fargo", ParseInventoryLine(inventoryLines[5])) }; // Read and parse Transactions.txt string[] transactionLines = File.ReadAllLines(transactionsFilePath); foreach (string line in transactionLines) { if (string.IsNullOrWhiteSpace(line)) continue; // Skip empty lines try { char type = line[0]; int itemNumber = int.Parse(line.Split(' ')[1]); int quantity = int.Parse(line.Split(' ')[2]); if (type == 'S') { // Find the warehouse with the largest supply of the item var targetWarehouse = FindWarehouseWithLargestSupply(warehouses, itemNumber); targetWarehouse.ProcessTransaction(type, itemNumber, quantity); } else if (type == 'P') { // Find the warehouse with the lowest supply of the item var targetWarehouse = FindWarehouseWithLowestSupply(warehouses, itemNumber); targetWarehouse.ProcessTransaction(type, itemNumber, quantity); } } catch (Exception ex) { Console.WriteLine($"Error processing transaction '{line}': {ex.Message}"); } } // Output final inventory status foreach (var warehouse in warehouses) { Console.WriteLine($"{warehouse.Name}: {string.Join(", ", warehouse.Items.Values)}"); } } public static int[] ParseInventoryLine(string line) { string[] parts = line.Split(' '); return new int[] { int.Parse(parts[0]), int.Parse(parts[1]), int.Parse(parts[2]), int.Parse(parts[3]), int.Parse(parts[4]) }; } public static Warehouse FindWarehouseWithLargestSupply(List warehouses, int itemNumber) { Warehouse largest = warehouses[0]; foreach (var warehouse in warehouses) { if (warehouse.Items[itemNumber] > largest.Items[itemNumber]) { largest = warehouse; } } return largest; } public static Warehouse FindWarehouseWithLowestSupply(List warehouses, int itemNumber) { Warehouse lowest = warehouses[0]; foreach (var warehouse in warehouses) { if (warehouse.Items[itemNumber] < lowest.Items[itemNumber]) { lowest = warehouse; } } return lowest; } } Explanation: This C# program manages the inventory of six warehouses for a wholesale distributor. It defines a Warehouse class to represent each warehouse, storing item quantities and providing a method to process transactions (sales and purchases). The Program class contains the Main method, which reads initial inventory data from Inventory.txt and transaction data from Transactions.txt . It initializes the warehouses, processes each transaction by updating the relevant warehouse's inventory, and handles sales by subtracting quantities and purchases by adding quantities. Finally, it outputs the updated inventory status for each warehouse, ensuring accurate stock management. Step 2: Output: Atlanta: 500, 120, 60, 0, 50 Baltimore: 100, 110, 1000, 50, 0 Chicago: 0, 75, 0, 0, 220 Denver: 600, 50, 120, 300, 40 Ely: 210, 160, 30, 80, 50 Fargo: 90, 50, 200, 70, 0 Output SS: Directory SS: Transactions.txt: P 410 1000 S 215 120 S 711 300 Inventory.txt 500 120 60 0 350 100 230 0 50 0 0 75 0 0 220 600 50 120 300 40 210 160 30 80 50 90 50 200 70 0 Explanation: The output shows the final inventory levels for six warehouses after processing transactions. Atlanta's item 711 reduced to 50 due to a sale. Baltimore's item 410 increased to 1000 due to a purchase, and item 215 decreased to 110 due to a sale. Chicago, Denver, Ely, and Fargo's inventories remained
