JavaScript library for Coliru online compiler
Add <script>window.onload = coliru.addRunButtons</script> to
your page to insert buttons into every C++ code block that will
compile and run the code and displays the result below the code block.
C++ code blocks are those <code> elements with the data-lang="c++"
attribute. For example:
<pre>
<code data-lang="c++">
int main()
{
return 0;
}
</code>
</pre>
