Dynamic source code in C++ [closed]

Answer 1

This is a good case for embedding an interpreted language like LUA. If you create LUA bindings to your C++ API, you'll be able to dynamically execute your code via LUA code from your application.

Answer 2

The C++ language itself is not able to do that directly. But you may use plateform specific functions to call any function in a given DLL, according to user input (or whatever). For example, on Windows, look for GetProcAddress() and LoadLibrary()
