The examples so far have all read the standard input and written the standard output, which are
automatically defined ...
Many programs read only one input stream and write only one output stream; for such
programs, input and output with getchar, putchar, and printf may be entirely adequate,
and is certainly enough ... the standard output of prog into the standard input of anotherprog.
Output produced by printf also finds its way to the standard output. Calls to putchar and
