Data structures are just ways to store multiple data values. Arrays, structs, enumerations, unions, queues, lists, and vectors are a few examples of data structures. In this unit, we will focus on a few simple structures. The array is one of the most basic structures used in computer programming. Arrays store data contiguously by representing data with a common name and distinguishing it by its index. This is like a parking garage: the garage stores vehicles; all of the parking spaces have a common name (the name of the garage); and each parked vehicle is identified by a specific parking space number. This is also true of arrays. Think of arrays as parking garages for our data. After exploring arrays, we then learn structs, unions, and enumerations, which are special ways to group more complex data types.
Completing this unit should take you approximately 8 hours.

Enumerated types (enums) are essentially a series of int variables that represent more complex data types.

Structs are a great way to pair multiple variables together and allow them to be passed as a group. Unions are very similar to structs, but the data shares the same memory spaces, so they cannot be used at the same time.
