Assign a reference outside the constructor

Is it possible to set the address of a reference outside of the constructor?

Code:

---

int& a = b;

---

works

Code:

---

int& a;
a = b;

---

Obviously just changes the value, not the reference.

Do you have something like?

Code:

---

class N
{
    int& a;
    public:
    N(int& b) {???}
};

---

You'll need to use the constructors initializer list:

Code:

---

    N(int& b): a(b) {}

---

Does that work outside of constructors, such as a method? Like this:

Code:

---

class ClassCache
{

private:
  ScriptManager& scriptManager;
  ..
  ..

public:
  ..
  ..
  void Assign(ScriptManager& scriptM): scriptManager(scriptM){}
};

EDIT: after a test, it turns out i HAVE to do that constructor initializer list thing for every object reference in the class. I guess its because its unsafe to have an unitialized object reference..?

The language forbids you from having uninitialized references.

If you need to change what the reference is referencing, you can always use pointers.

Yeah ill just leave it as a pointer. I can always do * to convert it to a reference or value.
