Setting passed ofstream to class wide variable

I have a constructor for my class: class(ofstream & o). I want to set my class variable ofstream out. The problem is I can't use out = o without getting an error.

What you'd do is something like:

   class MyClass
   {
      ofstream& out;
      MyClass(ofstream& o) : out(o)
      {}
      ...
    };

This will work, and internally you can use out as usual.

In your question, you say ofstream out. You cannot "copy" file streams, so you cannot say out = o unless out is a reference.
