\def\title{Listing 1}

@*A Simple Example.
This is a trivial example of a \.{CWEB} program.
It is, of course, the classic ``hello, world''
program we all know and love:

@c
@<Header files needed by the program@>@;
@#
main(void)
{
    @<Print the message |"hello, world"|@>@;
}

@ Naturally, we use |printf| to do the dirty work:

@<Print the message |"hello, world"|@>=
printf("hello, world\n");

@ The prototype for |printf| is in the standard
header, \.{<stdio.h>}.

@<Header files needed by the program@>=
#include <stdio.h>

@*Index.
