How to compile C++ code with iostream include

Question

I am trying to compile a small piece of C++ code with Visual Studio 2015,and when I include iostream library,I get some weird compile errors,Can anyone help me solve it ?

Here is my code

#include "stdafx.h"
#include <iostream>

int main()
{
    std::cout << "Somethig" << std::endl;
    return 0;
}

And here are the errors I get when I compile this

All helps will be appriciated.

An ICE is always a compiler bug. Something's wrong with your installation. How did you install VS2015? — Lightness Races in Orbit, May 03 '17 at 18:22

#include <cstdlib>

You should reinstall the visual studios because the only thing I think of why you code wouldn't compile would be is because you forget the library header

I did,same code compiles when I reinstalled the studio – Uğur KURT May 06 '17 at 19:54
@Uğur KURT-Have you tried downloading MinGW C++ compiler for windows 10? I have that currently. Let know if you decide to do that. Any time one software doesn't work for you, you can always try something else. – User445555 May 06 '17 at 20:28
