Is the destructor called if the constructor throws an exception?

Question

Looking for an answer for C# and C++. (in C#, replace \'destructor\' with \'finalizer\')

Answer 1

C++ -

Nope. Destructor is not called for partially constructed objects. A Caveat: The destructor will be called for its member objects which are completely constructed. (Includes automatic objects, and native types)

BTW - What you're really looking for is called "Stack Unwinding"
