How Do Dynamic Arrays Work?

In this tutorial, we are going to dive into dynamic arrays, how they work, how to implement them, and explain their most important features!

Before digging into dynamic arrays, we first need to make sure you understand what basic arrays are. An array is a type of data structure that has a fixed size, and they can store one or more values of a specific data type, called its elements.

An element of that array can be accessed by its index. The size is usually allocated on the array's definition, and static array lengths cannot be changed. This is a limitation which can make programming unnecessarily complicated, so that's why dynamic arrays were introduced.
