myswap函数本来是指针形参，改成引用后又异常。求高手解答

myswap函数本来是指针形参，改成引用后又错误。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(&ra,&rb);
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;

}


[解决办法]

C/C++ code

#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;}
[解决办法]
C/C++ code
&x=&y; //compile error&y=temp;
