Creation of the object is done in the constructor, though not in the
curly brackets.

You can do this:

class MyClass {
    boost::scoped_ptr<int> ptr;
  public:
    MyClass() : ptr(new int) { *ptr = 0; }
    int add_one() { return ++*ptr; }

    boost::scoped_ptr<int> newObject()
    {
        Ptr.reset( new int );
        *ptr = 0;
    }
};
