C and C based languages - Structures and Unions

Structures and Unions - C and C based languages module C209

Data doesn't come neatly packaged in a series of similar (homogenous) elements - instead, if you have a number of different attributes of a thing (or object), each of them may be of a different type (i.e. heterogenous). C's structs allow you to define your own data types as composites of other data types, with each individual member having a name and characteristics suitable to its particular data and function.
