Thread: fgets?

hi there.

could somebody tell me how to use fgets instead of scanf in the example below? thank you.

Code:

void read_date(int *yyyy, int *mm, int *dd) {
	int i;

	while(1) {

		printf("Enter date (YYYY MM DD): ");
		i = scanf("%d %d %d", yyyy, mm, dd);


		if(i == 3) {
			if((*yyyy < 1) || (*yyyy > 9999)) {
				printf("YYYY must be between 0 and 9999\n");
				continue;
			}
			if((*dd < 1) || (*dd > days_month[*mm-1])) {
				printf("DD must be between 1 and %d for the month of %s\n", days_month[*mm-1], months[*mm-1]);
				continue;
			}
			if((*mm < 1) || (*mm > 12)) {
				printf("MM must be between 1 and 12\n");
				continue;
			}


		} else {
			continue;
		}


		break;
	}

}

Code tags fixed by Hammer

i'm sorry. the code tags didnt work?

Code tags have [] around them not <>.

fgets() is not a replacement for scanf, it is a replacement for gets. It just reads a string in, no formatting. Try using fgets to read it in then sscanf to read from the string. It is a bit safer than just using scanf.

Code:

char buf[BUFSIZ]; /* BUFSIZ is defined in stdio.h */

printf("Enter date (YYYY MM DD): ");

if(fgets(buf, BUFSIZ, stdin) == NULL)
{
   ... /* error handling */
}
else
{
   i = sscanf(buf, "%d %d %d", yyyy, mm, dd);
   ...
}

thanx for fixing the code tags

is there anyway to do it without using sscanf either? i'm not trying to be a pain, but then it's part of the specs. please give me some clues and i'll try to work on it? thanx again.
