how do i post a code for a link such as <a href>, without making it work on my own page?

Answer 1

If you post a link as text, it will not function as a hyperlink unless you have programmed it to function as a hyperlink. You don't use the tag if you don't want it to work as a link.

Answer 2

To link to external pages, always use the full URL starting with http://

Otherwise the server thinks you are referring to an internal location.

Answer 3

write its exact url of that program or page.

Example:
< a href="http://www.pekiyi.150m.com/c.html">C examples

if you haven't internet connection, this command will not work.
