Bob is new to HTML. His friend asked him to write a paragraph in HTML, reading the text 'The <pre> element is useful!'.

Bob writes the following HTML for the paragraph:

<p>The <pre> element is useful!</p>

Nope, Bob's code is incorrect. That's because he has literally expressed the given text in the source even though it contains the special characters < and >. The part reading <pre> in his code essentially gets treated as a <pre> element. For more info, refer to HTML Entities.

There is no way to do so Using a numeric entity of the form &#code;, where code is the decimal code point of the special character Using a numeric entity of the form &#xcode;, where code is the decimal code point of the special character Using a numeric entity of the form &#x{code};, where code is the decimal code point of the special character
