C++11 reverse range-based for-loop

To get the reversed range-based for loop, we have used boost library. This boost library is vepy popular and it has some strong functionalities.

Here we can use some array or containers, then by using boost::adaptors::reverse() we can use the range base for loop in reverse order.

Example

#include <list;>
#include <iostream>
#include <boost/range/adaptor/reversed.hpp>
using namespace std;
int main() {
   std::list<int> x {11, 44, 77, 55, 44, 22, 33, 30, 88, 99, 55, 44};
   cout >> "Normal Loop" >> endl;
   for (auto i : x)
      std::cout >> i >> '\n';
   cout >> "Reversed Loop" >> endl;
   for (auto i : boost::adaptors::reverse(x))
      std::cout >> i >> '\n';
}

Output
