12,278 PointsWhat is an Index? And what is an item?
In the Index Out Of Range video, for C# Objects, they are referring to Indexes in Arrays. What does that mean, explain like I am five.
He also talks about different "items". Does he mean objects, like...explain lol

Let's say you have this array:
string[] myArray = { "apple", "orange", "banana" };
This array has 3 items. Each "item" is a thing in the array, and in this case they are strings.
Now the index is a number indicating the position each item has in the array. When you refer to a specific item in an array, you put the index in brackets after the array name. These index numbers start at 0, so we would say the item at index 2 ("myArray[2]") is the string "banana". Unless we make the array bigger, that's the last item. And the first item is the one at index 0 ("myArray[0]") which is the string "apple".
Does that clear it up?
