Local Variables
Local variables are not declared. Instead, they are created as needed. Local variables
are created either by being in a function's parameter list, or simply by being assigned a
value in a function body.
Function(Parameter)
{
Local = 20;
}
This function creates a local variable Parameter and a local variable Local, which has
an assigned value of 20.
2.3 Constants
A constant is similar to a variable, except that its value cannot be changed. Like variables,
constant names must contain only alphanumeric characters and the underscore ( _ )
character, and they cannot begin with a number.
Constants are declared similarly to global variables using the keyword const:
const CONSTANT = 20;
They can be assigned to any value type, but generates an error if used in the left-hand
side of an assignment statement later on. For example:
const constant_2 = 3;
Function()
{
constant_2 = 5;
}
generates an error.
Declaring a constant with the same name as a global, or a global with the same name as
a constant, also generates an error. Like globals, constants can only be declared in the
file scope.
