Not tested, but something like this:

// Resize result to accommodate elements
result.resize(src1.size());

// Add elements of both vectors and store result in third vector. 
// Assumes src1 and src2 have the same size.
std::transform(src1.begin(), src1.end(), src2.begin(), result.begin(),
(boost::lambda::_1 + boost::lambda::_2));
