You want the function `strcat', but its workings are somewhat different from
this. See its docs, and below.

The best ways are probably `sprintf' for number-to-string, and the `strtol'
family for the reverse. See docs.

The best solution is to get a book. I have heard good things about "The C
Programming Language, Second Edition" by Kerninghan and Ritchie. Look for
one that describes ANSI C, and not some specific compiler (i.e. Borland,
M$). Avoid like the plague any book whose title contains the words "Dummy"
or "Idiot".

Standard C questions like this really belong on the comp.lang.c newsgroup,
so that's another resource. Be sure to read its FAQ!

Incidentally, it's probably impolite to mail questions directly to DJ.
Posting to the newsgroup/list is a better approach.
