Structure
A structure is a package of
one or usually more variables which are grouped under a single name. Structures
are not like arrays: a structure can hold any mixture of different types of
data: it can even hold arrays of different types. A structure can be as simple
or as complex as the programmer desires.
The word struct
is a reserved word in C and it represents a new data type, called an aggregate
type. It is not any single type: the purpose of structures is to offer a tool
for making whatever shape or form of variable package that a programmer wishes.
Any particular structure type is given a name, called a structure-name and the
variables (called members) within a structure type are also given names.
Finally, every variable which is declared to be a particular structure type has
a name of its own too. This plethora of names is not really as complicated as
it sounds.
