This is a question that I\'ve always wanted to know the answer, but never really asked.

Answer 1

Typically the C++ code will invoke an interpreter for the scripting language. The degree of interaction between the compiled and scripting code is dependent on the interpreter but there's always a way to pass data between the two. Depending on the interpreter, it may be possible to manipulate the objects on one side from the other side, such as a C++ function calling a method on a Ruby object. There may even be a way to control execution of one from the other.
