Composite data type
open-in-new
<p>In <a href="/facts/Computer_science/lN3pEyPz">computer science</a>, a composite data type or compound data type is a <a href="/facts/Data_type/fcx5hgVL">data type</a> that consists of <a href="/facts/Programming_language/cWTYbgWa">programming language</a> <a href="/facts/Scalar_data_type/Rwma07cc">scalar data types</a> and other composite types that may be heterogeneous and hierarchical in nature. It is sometimes called a structure or a <a href="/facts/Record_(computer_science)/1fvSgenB">record</a> or by a language-specific keyword used to define one such as <a href="/facts/Struct_(C_programming_language)/mmhEWucA">struct</a>. It falls into the aggregate type classification which includes homogenous collections such as the <a href="/facts/Array_data_type/gHJJ3XPw">array</a> and <a href="/facts/List_(abstract_data_type)/9tzhAH6M">list</a>. </p>
