Question

Suppose in a method MA() of class A, a method MB() of class B is being called after creation of an object. Is there a way to know in MB() the name of the class and the method from which it is being called in C++ ??

Answer 1

What you are talking about is a Stack Trace.

Stack Trace definition:

The stack trace is a useful debugging
tool that you’ll normally take
advantage of when an exception has
been thrown. It provides information
on the execution history of the
current thread, displaying the names
of the classes and methods within
those classes that had been called at
the point when the exception occurred.
