RE: [Dev-C++] flexibla array

[Per W. <pw...@ia...>]

See missing line below.

By the way, I don't very much like variable names 'tmp' and 'tmp2'.

How about calling them 'current' and 'previous' or something similar,
since they represent the order of the entries when iterating through the
list.

And by the way - this is a normal dual-linked (forward+backward) list, not
a flexible (?)  array.

One more thing - why post a mail to a mailing list, claiming that the
contents of the mail is or may be proprietary? The only legalese that
might be suitable for mailing lists is that expressed oppinions are your
personal ones, and not necessarily the official ones of a
company/organisation/...

you are missing a
      tmp2->Next =3D tmp;
to let the previous tail point to the new entry
