- 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…13 2 Case a + 6 A- 13 N 13 2 Case b + 6 A-i should have said where; p=V^2/R P=[ML^2 T^-3] V=[L^0.5 M^0.5 T^-1] solve for R
- A 15-meter ladder is resting against a wall and makes an angle of 40 degrees with the ground. Find the height to which the ladder will reach on the wall in terms of a trigonometric function. a) O15 cos(40) [m] b) O15 cos(50) [m] c) O15 tan(40) [m] d) O15 sin(50) [m] e) ONone of the aboveA crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal (a). The atoms reside at the corners of cubes of side L=0.200nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken. Suppose this crystal cleaves along a face diagonal as shown in figure (b). Calculate the spacing d between two adjacent atomic planes that separate when the crystal cleaves.What is the outer diameter of the hollow cylinder shown in the image?
