boost-lambda

I have two vectors. vector<Object> objects; vector<string> names; These two vectors are populated and have the same size. I need some algorithm which does assignment to the object variable. It could be using boost::lambda. Let's say: some_algoritm(objects.begin(), objects.end(), names.begin(), bind(&Object::Name, _1) = _2); Any suggestion? I can't think of a std:: algorithm for this. But, you can always write your own: template < class It1, class It2, class Operator > It2 zip_for_each ( It1 first1, It1 last1, It2 result, Operator op ) { while (first1 != last1) op(*first++, *result++); return

I recently started looking at boost phoenix, as replacement for lambda. Is phoenix a full replacement for lambda, or is there some lambda functionality which is not provided by phoenix? is phoenix mature? Are there any gotcha I should know about? my primary interest are operator composition, control statements and casts are less so Thanks This post answers all your questions. Phoenix is very mature. Phoenix and lambda will be merged. It will be the base for future lambda implementations. 来源： https://stackoverflow.com/questions/2852775/boost-lambda-versus-phoenix

What might be the best way to start programming using boost lambda libraries. Remaining within the boundaries of the C++ language and libraries, I would suggest first getting used to programming using STL algorithm function templates, as one the most common use you will have for boost::lambda is to replace functor classes with inlined expressions inlined. The library documentation itself gives you an up-front example of what it is there for: for_each(a.begin(), a.end(), std::cout << _1 << ' '); where std::cout << _1 << ' ' produces a function object that, when called, writes its first argument

I can see that there are two different bind libraries for Boost, one "standalone", that can be used by including boost/bind.hpp , and another by including boost/lambda/bind.hpp . What's the difference between these two? Have a look at the explanation here: http://boost.org/doc/libs/1_46_0/doc/html/lambda/s08.html#id2143701 They have overlapping functionality but with semantic differences, they can't be used interleaved. 来源： https://stackoverflow.com/questions/5202974/what-is-the-difference-between-boostbind-and-boostlambdabind
