%hd 用于short integer或unsigned short integer

%hhd 用于short short integer或unsigned short short integer

%ld 用于long integer或unsigned long integer

%lld 用于long long integer或unsigned long long integer

就那么简单。

这里h, hh, l,ll只是 %d 中的长度修饰符

我认为IBM 的这份文档要好一些。所以：

  %hd       int x          (short)x           10     1
  %ld       long x         (long)x            10     1
