等于0才表示相等

Returns an integral value indicating the relationship between the strings:
return value indicates
<0 the first character that does not match has a lower value in ptr1 than in ptr2
0 the contents of both strings are equal
>0 the first character that does not match has a greater value in ptr1 than in ptr2
