In this one, I want to show you how to work with arrays and perform a handful of different functions on them. I'm going to start by naming my file here, just as a comment in my own file, and then I'm going to create an array. It's going to be integer variables and I put the square brackets to indicate that it's an array. Give it a name, I'll just simply call this one 'a', and then I'm going to put in curly brackets {7, 0, 4}, and those would be the three values that are going to be in my array.
