Removing items from an inventory!

[Pjonathan]

I have finally got inventory and items to work. I just now need to know how to remove an item from the inventory. If you could please help me by editing the code below that would be nice. I have spent 2 day just trying to find out how to remove the item from the inventory and have given up so if you can please help me find out how to remove the item from inventory.

I have marked where i want the remove option to be. :)

#include <iostream>
#include <string>

{

const int MAX_ITEMS = 10;
string inventory[MAX_ITEMS];
int choice, choice2, choice3, choice4, numItems = 0;

Thanks for all the help in advance! :)

EDIT: If you compile and run it makes more sense.

I'm writing this message on my mobile phone. So i can't compile it.

First, you should use vector instead of array.
Vectors have many useful methods like erase. And easily you can remove item from a vector(inventory).

[firedraco]

1) Don't use system()
2) Don't use goto, it's not required here
3) Your program design is not going to work, even with this little amount of code, it is already incredibly hard to read and very messy. I suggest you learn some OOP; it'll help you make it a lot simpler and easier to understand.

Well just so you guys know, I'm self teaching myself... so you would recommend being actually taught by a professional?
