    <p>It's really all across the board. On one end of the spectrum, I've worked in one place where the code was recently rewritten in C. Recently being 10 years ago. Everyone was highly skeptical of this new-fangled technology.</p> <p>Slightly farther down the spectrum, you'll find C programmers who happen to have compilers with C++ features enabled. They'll dabble in the "class" keyword. But other than that, they are practically writing in C.</p> <p>Next down the line I think you'll find those who just groked inheritance and polymorphism. These are the kind of guys and gals that would swoon over an MFC or wxWidgets program, thinking it was the greatest.</p> <p>You'll go a little farther and find the folks who just read Meyer. They are all about figuring out how to use STL efficiently. They've got a basic notion of templates that equates mostly to the way STL uses them.</p> <p>Then you've got the Modern C++ Template Metaprogramming geeks. Many of us these days use their work in the form of boost and all its goodness. Few actually dork around with template metaprogramming. That's probably a good thing.</p> <p>I have seen perfectly good code written at each level.</p> <p>The cool thing I always liked about C++ is that at each level of added complexity, the cost could be conceptualized in terms of "how this new abstraction might be implemented in C". So I can conceptualize that inheritance and polymorphism is adding the cost of a function pointer lookup. Since I have seen this and written this in C, I know what I'm in for. I also have a sense of how templates work in part because of how the preprocessor works in C. This applies to most features in the C++ and C world.</p> <p>Since it's easy to map concepts to how they are implemented in C, I can easily visualize how the underlying architecture runs my code.</p>

    1. COThis is a good rundown but doesn't answer the stated question: How do (or would) you try to determine a group's level of sophistication and commitment to C++ in the interview setting?

    2. COMaybe you are write, it seems the question has changed somewhat from the original title of "How many "real" C++ shops have you worked in?" with questions focused on our experience in the field. Its true I don't answer the second part about how to determine the level of development.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
