{{Short description|Computer code that is never executed}}
The term '''dead code''' has multiple definitions. Some use the term to refer to code (i.e. instructions in memory) which can never be executed at run-time.<ref>
In some areas of [[computer programming]], '''dead code''' is a section in the [[source code]] of a program which is executed but whose result is never used in any other computation.<ref>[http://doi.acm.org/10.1145/349214.349233 Debray, S.
