=== C ===

There is no standard implementation of an associative array in C, but a 3rd party library with BSD license is available [http://www.cl.cam.ac.uk/~cwc22/hashtable/ here]{{Dead link}} . [[POSIX]] 1003.1-2001 describes the functions <code>hcreate()</code>, <code>hdestroy()</code> and <code>hsearch()</code>.

Another 3rd party library, [http://uthash.sourceforge.net/ uthash], also creates associative arrays from C structures. A structure represents a value, and one of the structure fields acts as the key.
