[Boost-users] [lambda] newbie: lambda to help in std::accumulate

25 Jan 2009

      I want to compute sum of logarithms so i wrote:

#include <cmath>

double evaluate(const vector<double>& win_probabls)
{
 	return accumulate (win_probabls.begin(), win_probabls.end(), 0,
lambda::_1 + log(lambda::_2) );
}

but this code doesn't compile. Does anyone know why?
