は検討thisコード： #include <iostream>
using namespace std;
void Func(int&& i) {
++i;
}
int main() {
int num = 1234;
cout << "Before: " << num << endl;
Func(std::move(num));
co
このmove'ed： void foo(int &&r) {
std::cout << r << std::endl;
}
int main() {
int i = 2;
foo(std::move(i));
i = 3; //no warning. any way to get some warnings here?
return 0;
