字符串比较函数，一般形式为strcmp(字符串1，字符串2)。比较规则：对两个字符串自左至右逐个字符相比（按ASCII码值大小比较），直到出现不同的字符或遇到‘\0’为止。如果全部字符相同，则认为相等；若出现不相同的字符，则以第一个不相同的字符的比较结果为准。如果两个字符串都由英文字母组成，则有...

The return value for each of these functions indicates the lexicographic relation of string1 to string2*.* On an error, _mbscmp returns _NLSCMPERROR, which is defined in STRING.H and MBSTRING.H. Remarks The strcmp function compares string1 and string2 lexicographically and returns a value ind...
In summary, strcmp() does not necessarily use the ASCII code order of each character like in the 'C' locale, but instead parse each string to match language-specific character entities (such as 'ch' in Spanish, or 'dz' in Czech), whose collation order is then compared. When both ...
