Inventory System
Hello, Ive been working on this inventory for practice for quite some time now and this is the last thing i need to do ive been trying everything i know to get it to work. which is adjusting the supply for each item. I have gotten options 1 and 2 to work and save in thefile i close and open the file and press option 2 and the data saved in the file show up and it works. But when i try to edit the inventory(option 3) it doesnt work it wont save in the file and if it does the numbers are rediculous.
Lines 81 - 148.
Code:
#include <iostream>
#include <cstdlib>
#include <string>
#include <fstream>
#include <windows.h>
using namespace std;

cout << "\nAdd Item 1 ";
