Once a derived data type is defined, variables using that definition can be declared. The general format for a declaration is as follows:
type (<type_name>) :: <variable_name(s)>
For example, to declare two students, the following declaration could be used:
type (student) :: student1, student2
This declaration will declare two variables, student1 and student2, each with the set of components defined in the type definition. The definition can be thought of as the cookie cutter and the declaration is the cookie. Only after a variable has been declared, can values be set for that variable.
