我最近玩C中的位字段,显然,这些位从低到高排序,尽管谷歌不支持这一论点(例如维基百科).

#include <stdio.h>

struct bits {
    unsigned char a : 1;
    unsigned char b : 1;
    unsigned char c : 1;
    unsigned char d : 1;
    unsigned char e : 1;
    unsigned char f : 1;
    unsigned char g : 1;
    unsigned char h : 1;
};

int main(int argc, char **argv)
{
    unsigned char c = 33;
    struct bits *b = (struct bits *) &c;

    printf("dec: %u\n", c);
    printf("bits: %x", b->a);
    printf("%x", b->b);
    printf("%x", …
