Hello,
I'm having problems with string comparisons.
I have data like char d1[3] = {1, 2, 3} and char d2[1][3] = {1, 2,
3}. Now if I do strcmp(d1, d2[1]), it compares only the first
character, it seems. What is the correct solution?
Thanks,
andrej

How is {1,2,3} a string?
Remainder : "a string is an array of characters terminated by a 0".
You want (maybe)
char d1[] = {1, 2, 3, 0};
or more likely
char d1[] = {'1', '2', '3', 0};
or
char d1[] = "123";
3}. Now if I do strcmp(d1, d2[1]), it compares only the first character, it seems. What is the correct solution?
You must be sure that the adresses passed to strcmp() points to valid
strings.

A string is a sequence of characters that ends with a null character. I
don't see any strings in your example, and I can't figure out what you mean
to do. Maybe you should be using strncmp or memcmp? In any case, the
second argument to strcmp--d2[1]--produces undefined results. There is no
d2[1]. There is only d2[0].

How did you determine this? You obviously used more code than
described above.
What is the correct solution?
A string has a '\0' terminator. The crap you are passing to
strcmp() above doesn't, so it's not a string.
