Question

This prototype does not match the definition. How do i fix it? I threw a const on b.c. I thought that might do it. But not go

I know it needs the template designator in the definition even though it does not use the template…because this was a previous error.

// Prototype

template <class T> class dynamic_array
  {
  public:
    void print_operator(ostream)const;
  };

// Definition

template <class T> void dynamic_array<T>::print_operator(ostream &os=cout)const
  {
  for (int i = 0; i < size; i++) os << array[i] << endl;
  }

1. Your default argument is in the implementation, it should be in the prototype
2. The implementation takes a reference, the prototype needs to take a reference too
