Need help with removing a product from the list
Design and code a program that will maintain a list of product names. Use a String type to represent the product name and an array of strings to implement the list. Your program must implement the following methods:
Add a product to the list
Remove a product from the list
Display then entire list
Find out if a particular product is on the list.
You need to create a command command loop with a menu() function. The program must continue asking for input until the user stops.
This is the assignment and this is what I have so far. I need some help writing the remove function.
Thanks
