Variables are the basic building blocks of a program. They are effcetively a storage container for data of a certain type. More complex types are built out of a combination of such variables.

Declaring variables

Declaring variables is very simple and follows the following format:

<type> <identifier;

You can also assign to a variable whilst declaring it:

<type> <identifier> = <expression of <type>>;


You can update the stored value in a variable as so:

<identifier> = <expression of <type>>;
