Visual Studio 2019: C++ default language standard when nothing is checked

Question

_{Wednesday, May 22, 2019 8:43 AM}

The question is about project properties in VS 2019: C/C++->Language->C++ Language Standard: If nothing it checked there what option is the default?

To be more specific: which of the options available after mouse click is actually set? Is it C++17?

Hi friend,

Welcome to MSDN forum.

>>If nothing it checked there what option is the default?

Please check this document, if nothing it checked, C++14 is default for VS2019.

• By default, /std:c++14 is specified

To check it:

We can create a new C++ project, and std::cout << _MSVC_LANG; We can get the 201402 which indicates the C++14.

(For a new C++ project, the Language standard is empty by default. According to the value 201402 we could know C++14 is specified by default as the doc says)

>>To be more specific: which of the options available after mouse click is actually set? Is it C++17?

When you set a mouse click, both C++14 and C++17 is available.



Hope all above helps. Please give me a feedback if my reply is helpful:)

Best Regards

Lance
