Which programming language is used in Blender?

Question

As a guy that ALWAYS loved and still loves C++
Does Blender use C++ ?
Some people says Blender and other people says Python

Blender software source code is c++ (99% sure), Blender API use python (100% sure). https://docs.blender.org/api/current/ — Strapicarus, Nov 18 '17 at 21:29

Blender is written in 3 languages: C, C++, and Python.

C - for Blender's [startup/main-loop/shutdown] and most internal functionality, tools, drawing, GUI and editors.

C++ - physics, audio, game-engine and Cycles render engine.

Python - The interface definitions, addons, most format import/export and some tools.
