分享谁能解释下,什么是位段
#include <stdio.h>
struct bit
{
unsigned a_bit: 2;
unsigned b_bit: 2;
unsigned c_bit: 1;
unsigned d_bit: 1;
unsigned e_bit: 2;
unsigned word: 8;
};
int main()
{
struct bit *p;
unsigned int modeword;
printf(" enter the mode word (HEX):");
scanf("%x", &modeword);
p = (struct bit *) & modeword;
printf("\n");
printf("a_bit: %d\n",p->a_bit);
printf("b_bit: %d\n",p->b_bit);
printf("c_bit: %d\n",p->c_bit);
printf("d_bit: %d\n",p->d_bit);
printf("e_bit: %d\n",p->e_bit);
}
一点看不懂啊
