Is the "code" supposed to be in C++ or Python?

If it's in Python, then you need to link against the Python library and
use its C API. See the "Extending and Embedding" section in the Python
documentation. And direct further questions to a Python forum.

If it's in C++ ... well C++ really isn't that sort of language. It isn't
particularly meaningful to evaluate fragments of code in the sense of a
high-level language's eval() function.

If you just need some form of run-time extensibility which includes
expressions, you might want to consider Lua, as it's specifically
oriented towards embedding in larger programs.
