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。
