I would like to know if I can use transform and lambda to add 2 int vector and save the result into a third int vector

vector<int> src1; vector<int> src2;

vector<int> result // put the value of src1 and src2

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)); -delfin

You could, but that's simple enough that you don't even need lambda: assert( src1.size() == src2.size() ); result.resize( src1.size() ); std::transform( src1.begin(), src1.end(), src2.begin(), std::add<int>() ); The only thing lambda would do for you would be to let you say _1 + _2 instead of add<int>(). ~ Scott
