is it really necessary for character values to be positive?

How about in another posting then?

What I normally do is something more like

	char c;					/* yes, char! */
	....
	c = getc(stream);			/* or getchar() if stdin */
	if (feof(stream) || ferror(stream))
	 { ....
	 }

ie, *ignore* the EOF return and check explicitly.

Is this better? worse? than the int c; c=getc(stream); if (c==EOF)
approach?  Why?
