求两个输入数字的汉明距离

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include<assert.h>
int hammingDistance(int x, int y) {
    int b = x ^ y;//首先二者异或去求不同的位数
    int count = 0;
    int i = 0;
    for (i = 0; i < 32; i++)//要点是32位字节循环
    {
        if (((b >> i) & 1 )== 1)//按位右移一位与1与去确定不同的位数
            count++;

    }
    return count;
}
int main()
{
    int x = 0, y = 0;
    scanf("%d%d", &x, &y);
    int ret = hammingDistance(x, y);
    printf("%d", ret);
}
