c++将函数左旋转或右旋转

//将16位数字左旋转或右旋转
//original:0x2345
//rotate left 0x5234
//rotate right 0x3452

#include <iostream>
using namespace std;
unsigned short int rotate16Left(unsigned short int num, int n) {
    return (num >> n | num << (16 - n));

}

}
int main()
{
    unsigned short int num = 0x2345;
    printf("original:%#x\n", num);
    printf("rotated left:%#x\n", rotate16Left(num,4));
    printf("rotated right:%#x\n", rotate16Right(num,4));

    return 0;
