are they adding copy_if to c++0x?

Question

It\'s very annoying that copy_if is not in C++. Does anyone know if it will be in C++0x?

Answer 1

Just for completeness, in case someone googles his/her way to this question, it should be mentioned that now (in C++11 and later) there is a copy if algorithm. It behaves as expected (copies the elements in a range, for which some predicate returns true, to another range).

A typical use case would be

std::vector foo{ 25, 15, 5, -5, -15 };
std::vector bar;

// copy only positive numbers:
auto it = std::copy_if (foo.begin(), foo.end(), std::back_inserter(bar), 
            [](int i){return !(i<0);
          });
