使用宏反转4字节的字节顺序而不使用Zeros C++

#define SWAP_BYTES(x) (((x) & 0xFF) << 24) | (((x) & 0xFF00) << 8) | (((x) >> 8) & 0xFF00) | (((x) >> 24) & 0xFF)

// 示例代码
#include <iostream>

int main() {
    uint32_t num = 0x12345678;
    uint32_t reversedNum = SWAP_BYTES(num);
    
    std::cout << "Original Number: " << std::hex << num << std::endl;
    std::cout << "Reversed Number: " << std::hex << reversedNum << std::endl;
    
    return 0;
}
