Considering that the main Python implementation CPython written in C, and libraries exist that can convert Python code to C, would it be possible to run compiled Python bytecode in C or C++?
First, you cannot run anything in C, C is a programming language. You can embed python in your C program (see Documentation), because python can be compiled as library. But Python is not only the pyc-File, but consists of many modules, that make python as powerful as it is.
