===Variables===

'''Declaring a Variable'''

CGS variables are declared using this form of statement:

''datatype var_name;''

where datatype is the data type of the variable and var_name is its name. You can declare a variable of any valid types. When you create a variable, you are creating an instance of its type. Thus, the capabilities of a variable are determined by its type, and the type of a variable cannot change during its lifetime.

All variables in CGS must be declared prior to their use.

'''Initializing a Variable'''

You must give a variable a value prior to using it. One way to do this is through an assignment statement (see Operators - The Assignment Operator). Another way is by giving it an initial value when it is declared. The general form of initialization is shown here:

''type_name var_name = value;''

Here, value is the value that is given to var_name when var_name is created. The value must be of the type type_name.

Here are some examples:

''number n = 1;''

''string s = "hello";''
