Question

A college must track equipment items purchased using special funds.

Create an Inventory class that represents an equipment item. An equipment item consists of an 8-alphanumeric inventory number, a short description of the item, the purchase price of the item, and its current location (e.g.: room/building location). If an item is surplussed (e.g., gotten rid of), then the current location should say surplus, but the item should remain on the list.

Write a program that reads inventory items from a file into a vector. Implement a menu system that allows the user to add, edit, and delete records from the list as well as search the list based on inventory number and print a report of all records.
The list should always be maintained in order of inventory number. When the program closes, the data file should be overwritten with the most recent data from the list.

Implement one of the sorting and searching algorithms from the chapter. Do not use the built-in sort function.

Be sure to use the same menu options as shown in the example so the auto-grader can accurately grade your assignment.

Need the answer in C++ and always need a .cpp file, .h file, and driver file

Answer 1

Working code implemented in C++ and appropriate comments provided for better understanding.

Here I am attaching code for these files:

• main.cpp
• Inventory.cpp
• Inventory.h

main.cpp:

#include <iostream>
#include <fstream>

   bool stop = false, recordFound;
   int selection, recordNumber;

   vector<Inventory> partList;
   ifstream inputFile;
   inputFile.open("items.txt");

   if (!inputFile) {
       cerr << "Unable to open file items.txt";
       exit(1); // call system to stop
   }

   while(inputFile) {
       inputFile >> partNumber;
       inputFile >> name;
       inputFile >> price;
       inputFile >> location;
       partList.push_back(Inventory(partNumber, name, price, location));
