【C语言---12】编写函数： unsigned int reverse_bit(unsigned int value); 这个函数的返回值value的二进制位模式从左到右翻转后的值

思路分析:

数位遍历和迭代法的应用

#define  _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include <stdlib.h>
#include<math.h>

unsigned int reverse(unsigned int x)
{
	 int i;
	 int tmp, sum = 0;
	 for (i = 0; i < 32; x /= 2, ++i)
	 {
		  tmp = x % 2;
		  sum = sum * 2 + tmp;
	 }
	 return sum;
}

int main()
{
	 int n;
	 scanf("%d", &n);
	 int a =reverse(n);
	 printf("%u\n", a);
	 system("pause");
	 return 0;
}
