C++ Making my code actually print out to an output.txt

Hello,

I have managed to make my code create an output.txt file but I'm having issues making it print.

I have this now

int main()
{
  std::ifstream tokens_in( "input.txt" );
  std::ifstream dict_in( "dictionary.txt" );
  std::ofstream out( "output.txt" );
  auto filtered = filter(tokens_in, read_dictionary(dict_in));

  for (auto& token : filtered)
    std::cout << token << '\n';
}


When I run the script it creates an output.txt but doesn't print anything in it. It should be since it's being printed to CMD just fine.

How can I make this print out to an output.txt?

For example:

CMD will print out:
Word1
Word2
word3
word

Because it matched it in dictionary.txt and input.txt but in the output.txt there's nothing there.

No, because you're not writing to out anywhere.

  {  std::cout << token << '\n';
      out << token << '\n';  // Need to write to out as well as cout
  }

How do you do that? I'm new to this, not familiar with C++ really. This simple project has taken me 3 days and I'm still not done with it.

What would

  {  std::cout << token << '\n';
      out << token << '\n';  // Need to write to out as well as cout
  }


look like if it was written to out like it's suppose to?

(Sorry for asking to be spoonfed, I just honestly have no clue.)

I just gave you the code.

Line 2 writes the token to cout.
Line 3 writes the token to out.

Yes, I just tried it. Thanks so much!

I appreciate it a ton!
