Boost.Lambda is a Boost library to allow for lambda expressions to replace for-loops or to simplify their corresponding algorithm.


#include <algorithm>

#include <boost/lambda/lambda.hpp>





//From http://www.richelbilderbeek.nl/CppTriple.htm

template <class Container>

void Triple(Container& c)

{

  std::for_each(c.begin(),c.end(),boost::lambda::_1*=3);

}



#include <vector>

#include <cassert>



int main()

{

  std::vector<int> v;

  v.push_back(1);

  Triple(v);

  assert(v[0]==3);

}
