Create a C++ program for managing a grocery store's Inventory system. The Inventory information is stored in a text file named "grocery inventory.txt." Each line in the file represents a grocery item with the following format: "SKU, Name, Category, Quantity Price" The program should allow the user to add new items, update the quantity of existing Items, and display the total value of the inventory. Ensure that the program checks for the existence of "grocery inventory.txt" and handles cases where the file is empty. Utilize functions to organize your code effectively, with comments explaining each function's purpose. You can use data structures like arrays or structs to store and manipulate inventory data. The program should output the updated inventory information to a file named "updated_grocery_Inventory.txt." Ex: grocery Inventory.txt: 101, Apples, Fruits, 50, 0.75 102, Bread, Bakery, 20, 2.50 103, Milk, Dairy, 30, 3.99 (updated grocery inventory.txt after adding 100 packs of Eggs…
