#include <stdio.h>int puts(const char *s);
The puts() function writes the string pointed to by s, followed by a NEWLINE character, to the standard output stream stdout (see intro(3)). The terminating null byte is not written.
The fputs() function writes the null-terminated string pointed to by s to the named output stream. The terminating null byte is not written.
The st_ctime and st_mtime fields of the file will be marked for update between the successful execution of fputs() and the next successful completion of a call to fflush(3C) or fclose(3C) on the same stream or a call to exit(2) or abort(3C).
On successful completion, both functions return the number of bytes written; otherwise they return EOF and set errno to indicat the error.
Refer to fputc(3C).
