Unreferenced variable

An unreferenced variable in the source code of a computer program is a variable that is defined but which is never used. This may result in a harmless waste of memory (unless the compiler used detects the situation and does not allocate storage for the variable, perhaps also issuing a warning). Some coding guideline documents consider an unreferenced variable to be a symptom of a potential coding fault.
==Examples==
C:

int main(void)


In this example, j is an unreferenced variable.
