Title: sscanf and csv string.
Post by: Alessio on September 12, 2007, 04:04:49 PM

Hi,

I've a string like this:

char *string = "01/01/2004,00:30,-9999,-9999";

How can I use sscanf function to retrieve single values ?
The first and second must be string, the other doubles.
I use following code but it crash. Why ?

int result = sscanf(string, "%[^','],%[^','],%g, %g", string1, string2, d1, d2);

Thanks.

You need the addresses of d1 and d2.

Code Select


int main(void)
{
	char string1[90], string2[90];

	char *string = "01/01/2004,00:30,-9999,-9999";
	float d1, d2;
	int result = sscanf(string, "%[^','],%[^','], %g, %g", string1, string2, &d1, &d2);
	printf("%s %s %g %g\n", string1, string2, d1, d2);

	return 0;
}

John
