这是无格式短片的格式说明符，格式为
八进制，不适用于格式化为八进制的signed int。
* printf（）函数不提供OP想要的内容。如果你想要一个以八进制打印的
signed int，你可以这样做：
printf（"％c％o"，octal< 0？' ' - ''：''''，八进制< 0？-octal：octal）;
...虽然这可能会因octal而失败< -INT_MAX。

That''s the format specifier for an unsigned short to be formatted as an
octal, not for a signed int formatted as an octal.
The *printf() functions don''t provide what the OP wants. If you want a
signed int printed as an octal you can do this:
printf("%c%o",octal<0 ? ''-'' : '' '', octal<0 ? -octal : octal);
...although this may fail for octal < -INT_MAX.
