creating an ostream

Question

I am trying to create a c++ ostream for educational reasons. My test will be creating an ostream that acts like a ofstream would except instead of writing to a file it would

Answer 1

I'll just remark that you don't have to write an ostream-like class for that. You can use an adapter to achieve your goal.

For example, this code reads from istream and inserts each element into a vector:

vector V;
copy(istream_iterator(cin), 
     istream_iterator(), 
     back_inserter(V));
