C++: Ignore warnings C4996

[jwenjian]

C4996 occurs when the compiler encounters a function or variable that is marked as deprecated by using a __declspec(deprecated) modifier, or when you attempt to access a function, class member or typedef that has the C++14 [[deprecated]] attribute.

To ignore the warnings, do in below ways:

1. In cpp file

#pragma warning(disable : 4996)

2. In Commond line:
   Using the /wd4996 command line option.

3. In Visual Studio:

• Open the Property Pages dialog for your project. For information on how to use the Property Pages dialog, see Property Pages.
• Select the Configuration Properties, C/C++, Advanced page.
• Edit the Disable Specific Warnings property to add 4996. Choose OK to apply your changes.
