    Question C++ Interview Questions

    We are looking to create a few new articles on one of our sites. One of the articles is "Top Interview Questions for the {C++} Developer." We'll likely do this for Java, VB, C#, and other areas as well.

    So my question to you is.... What is one (or more) of the Interview questions you got when applying (or hiring) for a C++ position? Post it here in this thread!

    Thanks!
    Brad!
    (I'm going to create a similar thread for other languages on this forum as well. It will be interesting as well to see how responses might differ!)

    Re: C++ Interview Questions

    If you have a class derived from a base class, and each has a constructor and a destructor, what is the order that the constructors are called in when an object of the derived type is created? When the object is destroyed what is the order that the destructors are called in?

    What is the purpose of a virtual destructor?

    Well, be aware that lots of information already exists on this topic. Not only are there books but also comparisons of books, like here for example,

    Re: C++ Interview Questions

    but of course interviewers don't also read these books - do they?

    Personally, I prefer more 'open ended' discussion type questions - such as 'What is a race condition?', 'Describe Polymorphism', When would you not use the STL sort functions' etc. Rather than specific c++ syntax questions.
    All advice is offered in good faith only. All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS. You are ultimately responsible for the effects of your programs and the integrity of the machines they run on. Anything I post, code snippets, advice, etc is licensed as Public Domain https://creativecommons.org/publicdomain/zero/1.0/ and can be used without reference or acknowledgement. Also note that I only provide advice and guidance via the forums - and not via private messages!

    Re: C++ Interview Questions

    Brads question is what are specific questions you have been asked in an interview.
