I am going through Reference concepts in c++ and I am little confused by this statement in C++ Complete Reference.

So what is happening in this case:

```
    int  var = 10;
    int& ref = var;
    int& r_ref = ref;
    r_ref++;
    cout << "var:" << var << "ref:" << ref << "r_ref:" << r_ref << endl;

```

The output i am getting is: 

```
var:11  ref:11  r_ref:11

```
