Generic programming can be achieve by using the proprocessor to define the generic code, with macro expansion taking the role of ''instantiation''. Sometimes the non-standard extention "statement expressions" is used to simulate function like behaviour for generic code:</ins></div></td></tr> <tr><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>&lt;syntaxhighlight lang=&quot;c&quot;&gt;</div></td><td class="diff-marker"></td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>&lt;syntaxhighlight lang=&quot;c&quot;&gt;</div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div>#define <del style="font-weight: bold; text-decoration: none;">cbrt</del>(<del style="font-weight: bold; text-decoration: none;">x</del>) <del style="font-weight: bold; text-decoration: none;">_Generic</del>((<del style="font-weight: bold; text-decoration: none;">x</del>)<del style="font-weight: bold; text-decoration: none;">, long double: cbrtl, </del>\</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div>#define <ins style="font-weight: bold; text-decoration: none;">max</ins>(<ins style="font-weight: bold; text-decoration: none;">a,b</ins>) <ins style="font-weight: bold; text-decoration: none;">\</ins></div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">                              default: cbrt, </del>\</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">        ({ typeof </ins>(<ins style="font-weight: bold; text-decoration: none;">a) _a = </ins>(<ins style="font-weight: bold; text-decoration: none;">a</ins>)<ins style="font-weight: bold; text-decoration: none;">; </ins>\</div></td></tr> <tr><td class="diff-marker" data-marker="−"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #ffe49c; vertical-align: top; white-space: pre-wrap;"><div><del style="font-weight: bold; text-decoration: none;">                              float</del>: <del style="font-weight: bold; text-decoration: none;">cbrtf)(x</del>)&lt;/syntaxhighlight&gt;</div></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">          typeof (b) _b = (b); </ins>\</div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">          _a &gt; _b ?
