Question

What would be the decomposition diagram (Used to break program down into components visually. Can have as many components as needed. Defines functionality that will solve the problem – does NOT define a flow ) of this program:

C++ language

Also the test strategy, test plan, and initial algorithm. When i mean initial algorithm i mean no coding whats so ever. Just the logic.

2015 Fall CIS200-Lab 9-fos/AAH Release date: November 24, 2015 ek Due date: December 1, 2015 root 1, Aorta de Dec 12015 You need to write a program to keep inventory for a hardware store three ways You will write a program to store the inventory in (1) an unsorted linked list and (2) an unsorted array and (3) sorted array. Make the arrays big enough to store 100 records. bubble sor Each record will contain: stevc+ Record # (int), Tool Name (char [20]), Quantity (int) and cost (double) Your program should initialize the array to 100 empty records Then create a menu that allows you to Update a record, Delete a record, List a record, and list All tools (the se to sort Add Then create a menu that allows you to Update a record, Delete a record, List a record, and list ll tols (the ones that are not empty). Aber you add, ear ACher you add reser Start your inventory with the following information uantityCost 57.00 11.99 11.00 79.50 99.99 6.99 21.50 7.50 Record# Name Electric Sander # 7 76 21 17 24 39 56 68 Hammer Jig Saw Lawn mower Power saw Screwdriver Sledge hammer Wrench 18 106 83 34 Perform linear searches to perform the update, delete and list operations. For each operation write to an output file the number of comparisons necessary to perform each operation. After running your program for various inputs write a summary conclusion on the efficiency of performing the perations in the three ways
