二进制逻辑运算符有关练习题

//1.写一个函数返回参数二进制中 1 的个数#include<stdio.h>int div = 0;   //除数int rem = 0;   //余数int count = 0; //计1int count_one_bits(unsigned int div){    int con = 0;   //商    while (div >= 1)    {        con = div / 2;        rem = div % 2;        div = con;        if (1 == rem)        {            ++count;        }    }    return 0;}int main(){    printf("请输入一个数字");    scanf("%d", &div);    count_one_bits(div);    printf("%d", count);    return 0;}//2.获取一个数二进制序列中所有的偶数位和奇数位，分别输出二进制序列。#include<stdio.h>int main(){    int i = 0;    int j = 0;    int num = 0;    int arr1[16] = { 0 };    int arr2[16] = { 0 };    printf("请输入一个数字:\n");    scanf("%d", &num);    for (i = 0, j = 0; j < 32; ++i, j += 2)    {        arr1[15 - j / 2] = (num >> j) & 1;        arr2[15 - i] = (num >> (2 * i + 1)) & 1;    }    printf("%d对应二进制的偶数位分别是:\n", num);    for (i = 0; i < 16; i++)    {        printf("%d", arr1[i]);    }    printf("\n");    printf("%d对应二进制的奇数位分别是:\n", num);    for (i = 0; i < 16; i++)    {        printf("%d", arr2[i]);    }    printf("\n");    return 0;}//3. 输出一个整数的每一位#include<stdio.h>int main(){    int i = 0;    int num = 0;    int arr[32] = { 0 };    printf("请输入一个整数:\n");    scanf("%d", &num);    for (i = 0; i < 32; ++i)    {        arr[31 - i] = (num >> i) & 1;    }    printf("%d对应的二进制数字是:", num);    for (int i = 0; i < 32; ++i)    {        printf("%d", arr[i]);    }    printf("\n");    return 0;}//4.编程实现：//两个int（32位）整数m和n的二进制表达中，有多少个位(bit)不同？//输入例子 ://1999 2299//输出例子 : 7int main(){    int m = 0;    int n = 0;    int temp = 0;    int count = 0;    printf("请分别输入两个整数m,n\n");    scanf("%d%d", &m, &n);    temp = m ^ n;    int i = 0;    for (i = 0; i < 32; ++i)    {        if ((temp >> i) & 1)            ++count;    }    printf("%d和%d二进制表达式中有%d位不同\n", m, n, count);    return 0;}
