使用C ++回溯背包实现

Question

I am trying to implement backtracking knapsack solution with C++ which was from this website. But I get error at line std::move part, that says that std does not support move. Is there a solution for that? Is that because of my development environment?

 if (issol == true)
        {
            if (! vsol.empty()) vsol.clear();
            std::move(temp.begin(), temp.end(), std::back_inserter(vsol));
            temp.clear();
            issol = false;
        } else temp.clear();
        return;

Answer 1

std::move is a new feature starting from C++11 which requires including <utility> header file. So, check if you have #included this header file. Also, if you do not find this file then probably your development environment does not support C++11.

Reference: std::move

只包含实用程序

#include <utility>
