C strcmp() with one char difference

Question

My question is that how will strcmp() handle the following case:

strcmp("goodpassT", "goodpass");

I read that the comparison continues until a different character is found or null character (\0) is found in any of the strings. In the above case, when it encounters \0 for the second argument, will it just stop comparison, or will it still compare to the T character ? The return value is 1, but I'm not sure about the stopping condition.

Answer 1

The comparison is done using unsigned char. Thus the shorter string is smaller as its terminating 0 is smaller than other unsigned nonzero char in the longer string. See http://port70.net/~nsz/c/c11/n1570.html#7.24.4p1
