Variables are the way that our C++ games store and manipulate the values/data in our game. If we want to know how much health the player has, we need a variable. Perhaps you want to know how many zombies are left in the current wave? That is a variable as well. If you need to keep track of the name of the player who got a specific high score, you guessed it, we need a variable for that. Is the game over or still playing? Yep, that’s a variable too.

Variables are named identifiers to locations in memory. So, we might name a variable called numberOfZombies, and that variable could refer to a place in memory that stores a value to represent the number of zombies that are remaining in the current wave.

The way that computer systems address locations in memory is complex. Programming languages use variables to give a human-friendly way to manage our data in that memory. Managing a complex system in a human-friendly way is really what programming...
