C语言reverse二进制位的实现

#include <stdio.h>unsigned int reverseBits(unsigned int num) {    unsigned int count = sizeof(num) * 8 - 1;    unsigned int reverse_num = num;        num >>= 1;    while (num) {        reverse_num <<= 1;        reverse_num |= num & 1;        num >>= 1;        count--;    }    reverse_num <<= count;    return reverse_num;}int main() {    unsigned int num = 10; // 00000000000000000000000000001010    unsigned int reversed_num = reverseBits(num);    printf("Original number: %u\n", num);    printf("Reversed number: %u\n", reversed_num);    return 0;}

这段代码实现了一个函数reverseBits，用于将一个无符号整数中的二进制位逆序。在main函数中，我们定义了一个初始值为10的无符号整数，将其二进制位翻转后输出。
