Question

This may seem to defeat the purpose of a code block, but I’d like to be able to bold something within a code block. For example, if I wanted to bold the return line:

int main(void) {
    **return 0;**
}

You would have to do this in HTML,
by design.

However, inside Markdown code spans and blocks, angle brackets and ampersands
are always encoded automatically.

<pre>
int main(void) {
    <b>return 0;</b>
}
</pre>
