It definitely is possible, but you're trying it the wrong way.  Note the difference
between:

> printf( "\ncharacter %n == %s ", i, ch[i] ) ;
                            ^^^      ^^^^^
and:

               ^^^^

There's no "%s" format anywhere, in the fprintf() case. 

	fprintf(fp, "%s\n", ch[i]);

would have been closer to the goal. An alternative would have been

	fputs(ch[i], fp); fputc('\n', fp);

or	fputc(ch[i][0], fp); fputc('\n', fp);

Yes.  Strings *are* arrays in C.

Sorry, but without explaining what the "misbehaviour" was, it's hard
to help you here.
