The <pre> tag defines preformatted text.
Text in a <pre> element is displayed in a fixed-width font (usually Courier), and it preserves both spaces and line breaks.
In HTML proper, there’s no way short of escaping some characters:
& as &
< as <
(Incidentally, there is no need to escape > but people often do it for reasons of symmetry.)
The HTML <code> tag is used for indicating a piece of code. The code tag surrounds the code being marked up. The code being marked up could represent an XML element name, a filename, a computer program, or any other string that a computer would recognize.
