案例：C语言位域-证明高位在高字节，低位在低字节

注：参考自尹成CPP课程

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
struct BitType
{
	unsigned char ch1 : 1;
	unsigned char ch2 : 1;
	unsigned char ch3 : 1;
	unsigned char ch4 : 1;
	unsigned char ch5 : 1;
	unsigned char ch6 : 1;
	unsigned char ch7 : 1;
	unsigned char ch8 : 1;
};
int main()
{
	//int num; scanf("%d", &num);
	double num; scanf("%lf", &num);
	int len = sizeof(num);
	struct BitType* pb = (struct BitType*)&num;
	while (len--)
	{
		printf("%d%d%d%d %d%d%d%d\n",
			(pb + len)->ch8,
			(pb + len)->ch7,
			(pb + len)->ch6,
			(pb + len)->ch5,
			(pb + len)->ch4,
			(pb + len)->ch3,
			(pb + len)->ch2,
			(pb + len)->ch1);
	}
	return 0;
}
