Lisp macro special use?

I recently read a book by hackers and artists. The author said that the Lisp macro is very powerful and special than another language macro.

I started to study the ELisp macro, but still don’t see what use is it? I do not see the difference between it and the C / C ++ macro.

Can anyone explain this to me?

- C/++:

(defmacro bif ((var expression) then &optional else)
  `(let ((,var ,expression))
