Editing Backtick (section)

=== Markup languages ===
It is sometimes used in [[source code comments]] to indicate code, e.g.,

: <pre>/* Use the `printf()` function. */</pre>

This is also the format the [[Markdown]] formatter uses to indicate code.<ref>{{Cite web|url=http://daringfireball.net/projects/markdown/syntax#code|title = Daring Fireball: Markdown Syntax Documentation}}</ref> Some variations of Markdown support "fenced code blocks" that span multiple lines of code, starting (and ending) with three backticks in a row (<code>```</code>).<ref>{{cite web |url=https://github.github.com/gfm/#fenced-code-blocks |title=GitHub Flavored Markdown Spec |access-date=23 February 2022 |archive-url=https://web.archive.org/web/20220221045705/https://github.github.com/gfm/#fenced-code-blocks |archive-date=21 February 2022 |url-status=live}}</ref>

* [[TeX]]: The backtick character represents curly opening quotes. For example, <code>`</code> is rendered as single opening curly quote ({{not a typo|‘}}) and <code>``</code> is a double curly opening quote ({{not a typo|“}}). It also supplies the numeric ASCII value of an ASCII character wherever a number is expected.
