Ok here is what I got so far.
When you type add, it asks what object would you like to add
When you type list, it lists those objects
When you type exit, you leave the program
What I would like to do is create a search function where I can type in the name of an object that is on the list and it will come up on the screen.
I would like at LEAST an explanation of how this would be done if I can't have an example.
I know it has something to do with a loop and iteration but my mind is drawing a blank right now. Any help would be greatly appreciated!
