A structure is a collection of simple variables grouped together under a single name. It allows grouping of related data. Structures can contain nested structures and members are accessed using the dot operator. An example shows a structure used to store room measurements with nested structures for length and width. Enumerations are user-defined data types that allow a set of named constants.
