Lecture Outline

• A data structure is simply just a way to store and manage data
• There are many types of data structures. Each have their own pros/cons and use cases. It is important to be aware of the many types of data structures, and how to use them
• Arrays are not resizeable. To add something to an already full array, we must create a new array and copy the contents of the old array into the new array
• There is a built-in tool in your IDE called the Debugger. It steps through your program line-by-line, and displays the contents of all the variables
• By explaining your code to a rubber duck, it can help you get a better understanding of your code and potentially fix bugs
