    Talk:cpp/algorithm/swap

    From cppreference.com

    Which header

    std::swap is defined in header <algorithm> in C++03 (25.2.2[lib.alg.swap]) but in header <utility> in C++11 (FDIS 20.2.2[utility.swap]). How can that difference be expressed? --Cubbi 11:25, 23 August 2011 (PDT)

    Possible implementation

    Would it be OK to add a "possible implementation" section? 

    template<class T>
void swap(T& lhs, T& rhs) {
    T tmp = move(lhs);    // T satisfies MoveConstructible
    lhs = move(rhs);      // T satisfies MoveAssignable
    rhs = move(tmp);      // T satisfies MoveAssignable
}
