- C语言%hhu %hu 等含义区别 - 百度知道
C语言％hhu、％hu区别为：输出类型不同、占用空间不同、数值范围不同。 一、输出类型不同 1、％hhu：％hhu的输出类型为用于输出一个unsigned short短 整型 的数值。 2、％hu：％hu的输出类型为用于输出一个unsigned short int整型的数值。 二、占用空间不同 1、％hhu：％hhu的占用空间为一个字节。 2、％hu：％hu的占用空间为两个字节。 三、数值范围不同 1、％hhu：％hhu的数值范围为
- Inconsistency with %hhu format specifier in C printf function?
As far as I had understood it, the %hhu format specifier should have the range of an unsigned char However, in some compilers I test it in, it seems to have the range of an unsigned short instead

- What is the format specifier for unsigned short int?
For scanf, you need to use %hu since you're passing a pointer to an unsigned short For printf, it's impossible to pass an unsigned short due to default promotions (it will be promoted to int or unsigned int depending on whether int has at least as many value bits as unsigned short or not) so %d or %u is fine You're free to use %hu if you prefer, though
- c - given an %hhu and an input 1025, which part is mapped to an . . .
Is the output of the following programm 1 or 0, or is it undefined behaviour? int main() { unsigned char u = 10; sscanf("1025","%hhu", amp;u); printf("u, is it 0 or
- c - printf (), unsigned char, and %hhd - Stack Overflow
9 The format "%hhd" is for a signed byte If you pass an unsigned byte then you technically have undefined behavior To print an unsigned byte you need to use "%hhu" What really happens is because of how two's complement integers work, and that 0xff is equal to -1
- What is the need of hh and h format specifiers? - Stack Overflow
@StephenCanon: I expect so, but I am having difficulty interpreting C 2011 7 20 1 1: “When typedef names differing only in the absence or presence of the initial u are defined,…” I am wondering whether an implementation could provide uint8_t but not provide int8_t, due to stubbornness, and then not be compelled by 7 20 1 1 to make uint8_t be an unsigned char or char Then the implementation could provide another integer type, say __byte, that is an unsigned 8-bit integer but is
