I have a c++ project that involves making a invetory of items (like a store) with the items names, prices, add item, remove item, sell item, buy item and save all the data. The project must must be completed using maps, vector, stacks, and queue. please I need help in completing this project I have not idea of how to start it, I was thinking in doing classes and a final main.cpp. I could use maps to list all the items and a vector to store those items but I dont know how to do it, please I need help is fine if not all the structures are use such as maps, vector, stacks, and queue but at least two of the four .
