C++ Learn to use stream_iterators

Try not to use explicit loops, but prefer the standard algorithms.

One easy way to practice with this is using the stream_iterators:

int main()
{
    std::vector<int>   data;

    // copy a stream of numbers from standard input to 
    // vector, then back out to the standard output.

    std::copy(std::istream_iterator<int>(std::cin),
              std::istream_iterator<int>(),
              std::,back_inserter(data)
             );

    std::copy(std::begin(data), std::end(data),
              std::ostream_iterator<int>(std::cout));
}

Header needed for the above code:

#include <vector>
#include <ostream>
#include <algorithm>
#include <iterator>
