How to use the time function in C Language?

Answer 1

hey you need to include time.h file...

Answer 2

time_t t;

t = time(NULL);  /* or   time(&t); */

in either case, time returns (time_t)-1 when error occurs.

if ((t = time(NULL) < 0) {

/* codes on error */

} else {

struct tm *ptm;

ptm = localtime(&t);

priintf("%s\n", asctime(ptm));

}
