Hello,
can someone explain the C++ code snippet here
https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/nf-sysinfoapi-getintegrateddisplaysize
it says it is C++, could it be somewhat else?
Thanks

This prints nothing for me:

#include <Windows.h>
#include <iostream>

using namespace std;

int main()
{ double inches;
HRESULT ret = GetIntegratedDisplaySize( &inches );
if( FAILED(ret) )
return EXIT_FAILURE;
cout << inches << endl;
}

"C++" is specified just to select C++-ish syntax highlighting scheme.
The language is not C++.

The

Platform::String^ buffer;

declaration hints that it is C++/CX, an MS "extension" to C++ used to
create "UWP" apps. Not exactly current or standard.
