    int x = 10, y = 20;
    int *ptr = &x;
    int &ref = y;

    *ptr++;
     ref++;    

    cout<< x << " " << y;
    return 0; 
}

Here *ptr holds the value of x means *ptr =10.
*Ptr++ =11.
But it doesn't change the value of x.
But &ref=y (is alias) means ref=y.
So ref++ means y++.
So the output is the value of x is 10.
And y is 21.
