An example of moving from a const reference and what that does to the original variable

moveit.cpp

#include <string>
#include <iostream>
#include <cstdlib>

void moveit(std::string& s)
{
    std::string mys = std::move(s);
}

int main(void)
{
    std::string s = "hi";
    std::cout << s << std::endl;
    moveit(s);
    std::cout << "after move"<<std::endl;
    std::cout << s << std::endl;
    return EXIT_SUCCESS;
}
