Declaring and storing data in the array or list is very clear to us now. The next thing to learn is how to get stored elements from an array. To get a stored element from the array, write an array variable name followed by square brackets. You must write an int value within the brackets. That value is called an index. The index is simply a position in the array. So, to get the first element stored in the array, we will write the following code:

myArray[0];

Unity will return the data stored in the first place in myArray. It works exactly the same way as the return type methods that we discussed in the previous chapter. So, if myArray stores a string value on index 0, that string will be returned to the place where you are calling it. Complex? It's not. Let's show you by example.

Let's extend the familyMembers example:

I want to talk about line 20. The rest of it is pretty obvious for you, isn't it? Line 20 creates a new variable called thirdFamilyMember and assigns the third value stored in the familyMembers list. We are using an index value of 2 instead of 3 because in programming, counting starts at 0. Try to memorize this; it is a common mistake made by beginners in programming.

Go ahead and click on Play. You will see the name Adam being printed in the Unity Console. While accessing objects stored in an array, make sure you use an index value between zero and the size of the array. In simpler words, we cannot access data from index 10 in an array that contains only four objects. Makes sense?
