Cannot find any header files c++ project in Visual Studio

Question

For the past hour I have been looking at multiple stack overflow questions trying including this one and this one trying to figure out why visual studio cannot open typical source files like stdio.h

I am starting out by building a new project and then selecting the "console app" option, but when I try to compile and run the simple hello world program I get the errors shown below.

Edit :

Here is the code that is generated by default when choosing the console application option in visual studio that I am trying to run:

#include <iostream>

int main()
{
    std::cout << "Hello World!\n";
}

Answer 1

The issue was that I thought I had the Widows 10 SDK installed, but apparently I did not. I found the answer using this stack overflow thread.

I had to download the Windows 10 SDK from here and restart the visual studio IDE and it worked straight away.
