C strcmp() 有一个字符差异

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

Answer 2

The answer for this function strcmp("goodpassT", "goodpass");will be 1 only.The point upto which lengths of both the string are same will be compared on the basis of their ASCII value.
