When you create and name a variable, you're creating a placeholder for the value that you want to store. Let's take the following simple math equation as an example:
2 + 9 = 11
Okay, no mystery here, but what if we wanted the number 9 to be its variable? Consider the following code block:
myVariable = 9
Now we can use the variable name, myVariable, as a substitute for 9 anywhere we need it:
2 + myVariable = 11
If you're wondering whether variables have other rules or regulations, they do. We'll get to those in the next chapter, so sit tight.
Even though this example isn't real C# code, it illustrates the power of variables and their use as placeholder references. In the next section you'll start creating variables of your own, so keep on rolling!
