In the previous chapter, we saw how variables are written and touched on the high-level functionality that they provide. However, we're still missing the syntax that makes all of that possible. Variables don't just appear at the top of a C# script; they have to be declared according to certain rules and requirements. At its most basic level, a variable statement needs to satisfy the following requirements:

• The type of data the variable will store needs to be specified.
• The variable has to have a unique name.
• If there is an assigned value, it must match the specified type.
• The variable declaration needs to end with a semicolon.

The result of adhering to these rules is the following syntax:

dataType uniqueName = value;
