Overloading vs. Default Args

void error(char *message)

{

fprintf(stderr, “You have one message waiting. It is:\n”);

fprintf(stderr, “%s\n”, message);

}

void error(char *message, int copies)

{

while (copies--)

fprintf(stderr, “Copy %d: %s\n”, copies, message);

}

// print this message once

error(“mass of the universe exceeded maximum allowed value”);

// print 1,000 copies of this message (very annoying)

error(“energizer bunny keeps going and going…”, 1000);

Note that the same error function is used for both messages in the default arg example; different functions are used here.
