I'm not sure about the validity of the construct 'chcnt++ += (c == '\n');', but
I'd write your program scrap as:

        while ( (c = getchar) != EOF)
            {
            if (c == '\n')
                chcnt++;
            chcnt++;
            }

(Before closing, there is one logic flaw in your scrap of code. '(c == '\n')'
does not have to evaluate to an integer 1. It must only be a non-zero value if
true.)
