In this section, we're going to take our first look at a special class of objects called Data Structures, which are containers that can hold more than one element. In C++, the most fundamental of these data structures is the array. We have two types of arrays that we will be looking at. First, the built-in in array, also called C-style arrays because they exist in the C programming language, which is C++'s predecessor. We will also look at the array class which is a type provided only in C++. We will also look at the vector class as well, which allows us to create containers that resize as necessary to accommodate more data. We won't go in depth into classes and Object-Oriented Programming in this section, but using these classes will help us learn more about how objects work. I'm looking forward to all the new skills and knowledge we're going to pick up in this section, starting in the next lecture where we begin our discussion with built-in arrays. We have some really cool projects at the end too that use the array and vector classes, and also a technique called parallel vectors, which is used in a lot of industry programming. Let's get going!
