How to do it...

In this section, we will use different variants of std::copy:

1. Let's first include all headers we need for the data structures we use. Additionally, we declare that we use the std namespace:

       #include <iostream>       #include <vector>       #include <map>       #include <string>       #include <tuple>       #include <iterator>       #include <algorithm>       using namespace std;

2. We will use pairs of integer and string values in the following. In order to nicely print them, we should first overload the << stream operator for them:

       namespace std {       ostream& operator<<(ostream &os, const pair<int, string> &p)       {           return os << "(" << p.first << ", " << p.second << ")";       }       }

3. In the main function, we fill a vector of integer-string pairs with some default values. ...
