The puts() function shall write the string pointed to by s,
followed by a <newline>, to the standard output stream stdout.
The terminating null byte shall not be written.
The st_ctime and st_mtime fields of the file shall be marked for
update between the successful execution of puts() and the next
successful completion of a call to fflush() or fclose() on the
same stream or a call to exit() or abort().
The following example gets the current time, converts it to a string using
localtime() and asctime(), and prints it to standard output
using puts(). It then prints the number of minutes to an event for
which it is waiting.
#include <time.h>#include <stdio.h>...time_t now;int minutes_to_event;...time(&now);printf("The time is ");puts(asctime(localtime(&now)));printf("There are %d minutes to the event.\n", minutes_to_event);...
