分享一下這比較少用的用法，(也或許只是我自己比較少用到這)

說不定其實很多人都會了。


│bit_0 │bit_1│bit_2 │bit_3│bit_4 │bit_5│bit_6 │bit_7  │                       


#include <iostream>
using namespace std;

class bit_trace
{
public :
    bit_trace();
    unsigned char b_0:1;
    unsigned char b_1:1;
    unsigned char b_2:1;
    unsigned char b_3:1;
    unsigned char b_4:1;
    unsigned char b_5:1;

    unsigned char b_7:1;
};
bit_trace::bit_trace()
{
    b_0 = 0;
    b_1 = 0;
    b_2 = 0;
    b_3 = 0;
    b_4 = 0;
    b_5 = 0;
    b_6 = 0;
    b_7 = 0;
}
int main()
{
    bit_trace test;
    cout << sizeof test;
    return 0;
}
