What is wrong with this program?

Well, you can always use:

	printf("%.*s", sizeof (utmp.ut_name), utmp.ut_name);

or if you want exactly sizeof (utmp.ut_name) characters:

	#define NMAX (sizeof (utmp.ut_name))

	printf("%-*.*s", NMAX, NMAX, utmp.ut_name);

(The "-" gives "left adjustment"---blank filling at the right.)
