How to do it...

We are going to build up a cheap dictionary of one-to-one mappings from English words to their German translations, and store them in std::deque structures. The program will read such a dictionary from a file and one from standard input, and print one large merged dictionary on the standard output again.

1. There are a lot of headers to include this time, and we declare that we use the std namespace:

      #include <iostream>      #include <algorithm>      #include <iterator>      #include <deque>      #include <tuple>      #include <string>      #include <fstream>           using namespace std;

2. A dictionary entry should consist of a symmetric mapping from a string in one language to a string in another language:

      using dict_entry = pair<string, string>;

3. We are ...
