Using sscanf ( ), how to extract date from buffer that contain combined date and time ?
iso8601_date_time_buf is pointer to const char. It's length is Twenty bytes. It contains combined date and time in format: YYYY-MM-DDTHH:MM:SS
T is delimiter between date and time.
A delimiter is followed by first two %d. Do I need a delimiter after 3rd %d because day is in the middle of the buffer.

int year;
int month;
int day;
sscanf (iso8601_date_time_buf, "%d-%d-%d", &year, &month, &day );A delimiter is followed by first two %d. Do I need a delimiter after 3rd %d because day is in the middle of the buffer.

Just in cae I misunderstood your question: Using 'sscanf()', it's necessary to parse all the variable parts of your input string, otherwise you'll run into trouble.
Or, a bit more general, independant from the parsing method you choose (and there are plenty): You have to parse all variable fields in order to achieve a correct result, since otherwise all methods are doomed to fail at these very fields by definition.

Question answered. sscanf ( ) explained very well.
Thanks for alternate solution, istringstream class.
