aggregate type definition programming
A data type
composed of multiple elements. An aggregate can be homogeneous (all elements have the same type) e.g. an array
, a list in a functional language
, a string of characters, a file; or it can be heterogeneous (elements can have different types) e.g. a structure
. In most languages aggregates can contain elements which are themselves aggregates. e.g. a list of lists.
