#include <iostream>

using namespace std;

int main()
{
    cout << typeid(int).name() << endl;
    cout << typeid(int&).name() << endl;
    cout << typeid(int&&).name() << endl;
}

The output is:

int

int

int

My compiler is clang 5.0.

Why are the typeids of int, int&, and int&& same?

`typeid` ignores top-level qualifiers. – Kerrek SB Mar 25 '17 at 16:05
Not the issue, but don't use `std::endl` unless you need the extra stuff that it does. `'\n'` ends a line. – Pete Becker Mar 25 '17 at 18:50
