In which programming language/s are DirectX & OpenGL written (specially their core part like Kernel)?

    At least for OpenGL, there is no 'official' implementation. OpenGL itself is a specification, which can be implemented in any language. – HolyBlackCat Mar 01 '19 at 10:02

DirectX? Mostly a mix of C and C++

OpenGL? English, because OpenGL itself is just a specification document, written in technical prose. Most of the OpenGL implementations out there are also written in a mix of C and C++.

Both OpenGL and DirectX are specifications of an API. They are not limited to one programming language. Different implementations might use different languages.

OpenGL is typically implemented by system libraries or provided by your graphics driver. If you are interested in the programming language you have to check which one is used by your specific implementation.

For DirectX the implementation on Windows might be the most common, but it is not the only one. For example emulators or the WINE runtime environment for windows programs on linux also implement the DirectX API (which in many cases is done by using the OpenGL implementation of the underlying host system).
