Question

Hi I'm doing a c++ final project that is due on wed, the project involves makeing an inventory so far I created a sign in and new user functions to be able to save the items the that user buys under his name and password. However, iIneed in inventory.cpp a fucntion to delete an item if the user want to, also a fucntion to find or search an item by the user inputing the item ID or brand (I was thinking to use maps). Im using files to read and write the items names, prices, Id, and brand. The program that I have is not well done, and needs a lot of improvement, I need help to finish this project. Overall, the project is a inventory and im a file to read and write and save all the items information, the project need to have a add, remove, seacrh or find an item based on user inputing its id or brand, also include a total price of the things the user bought, also I need to use maps in some way. PLEASE I NEED HELP! take a look of the program I have so far. Please run the program to have a better view of what the project is about. Please I need help to have a program runing
