Yesterday I upgraded to the latest VS Community 2017 (the previous one was installed last year) and wanted to check the C++ standard. So I run the following code that checks it, and as it turns out, I have C++98:
#include<iostream>
using namespace std;
int main()
cout << __cplusplus << endl;
system("pause");
Which outputs
199711
Why don't I have the latest C++ standard?

You should build with/std:c++17and/permissive-for example.

Don't trust__cplusplus. VS2017 supports C++17 just fine - you just need to pass the correct commandline option(s) to enable it.

The value of __cplusplus is temporarily intentionally non-conformant by default for current versions of Visual Studio in order to avoid breaking existing code. It does not mean your compiler does not support any C++11 (or newer) features.
Quoting from MSVC now correctly reports __cplusplus:
/Zc:__cplusplus
You need to compile with the
/Zc:__cplusplusswitch to see the updated value of the__cplusplusmacro. We tried updating the macro by default and discovered that a lot of code doesn’t compile correctly when we change the value of__cplusplus. We’ll continue to require use of the/Zc:__cplusplusswitch for all minor versions of MSVC in the 19.xx family.

success! I followed the instructions on setting /Zc:__cplusplus to enabled and I see I have c++14 (201402). This is the guide for doing this: docs.microsoft.com/en-us/cpp/build/reference/…

If the actual standard the compiler is enforcing is the focus of concern, rather than the value of that macro, you can right click on your Project in the Solution Explorer. and SelectProperties. Then expand theC/C++menu on the left, and choose theLanguagesubmenu. There you can choose++14,++17, or++latest.
