Title
Body
for_each accepts InputIterators : //from c++ standard template <class InputIterator, class Function> Function for_each (InputIterator first, InputIterator last, Function f); is it ok to change the object in Function f, like this : struct AddOne { void operator()(int & x){x = x + 1;} }; std::vector<int> vec(10); std::for_each(vec.begin(),vec.end(),AddOne()); This code works in VC++2008 and also with GCC, but is it also portable (legal) code ? (InputIterators are only guaranteed to be usable as rvalue, in this case they are used as lvalue in AddOne's operator())
