myswap函数本来是指针形参，改成引用后又异常。求高手解答

#include<iostream>
using namespace std;
void myswap(int& x, int& y);
int main()
{
    int a=16,b=48;
    /*int& ra=a;
    int& rb=b;*/
    cout<<"a="<<a<<", b="<<b<<endl;
    myswap(a,b);
    cout<<"After Being Swapped:\n";
    cout<<"a="<<a<<", b="<<b<<endl;
    return 0;
}
void myswap(int& x, int& y)
{
    int temp=x;
    x=y;
    y=temp;

}

------解决方案--------------------

C/C++ code

&x=&y; //compile error
&y=temp;
