#include <stdio.h> /* header file */
main () /* Trivial program */
{
/* This little line has no effect */
/* This little line has none */
/* This little line went all the way down
to the next line,
And so on...
And so on...
And so on... */
do_little();
printf ("Function 'main' completing.\n");
}
/**********************************************/
/* A bar like the one above can be used to */
/* separate functions visibly in a program */
do_little ()

/* This function does little. */
printf ("Function 'do_little' completing.\n");
}
Again, this example is old-fashioned C, and in mediocre style. To make
it more compliant with the ANSI Standard and GNU guidelines, we would
declare the variable type each function returns (int for
main, which also requires an exit or return
statement), and we would create function prototypes at the beginning of
the file. (See Functions.)
