Interviews: Ask Bjarne Stroustrup About Programming and C++

In addition to being the creator of C++, Bjarne Stroustrup is a Managing Director in the technology division of Morgan Stanley, a Visiting Professor in Computer Science at Columbia University, and a Distinguished Research Professor in Computer Science at Texas A&M University. Bjarne has written a number of books and was elected a member of the National Academy of Engineering. He will be doing a live Google + Q & A within the C++ community on August 20th, 2014 at 12:30pm EST, but has agreed to answer your questions first. As usual, ask as many as you'd like, but please, one per post.

Re:Is the complexity of C++ a practical joke?

A practical joke? Are you joking? C++ is not designed so that every feature must be learned and used. It's complexity derives from the fact that it supports OOP, functional programming, generic programming and I'm sure others that Bjarne would happily describe to you and the reasoning behind supporting features being included in the language. Those that are confused by C++'s complexity are doing it wrong. As with Perl it's OK to use only what you're comfortable with, no one is going to make fun of you for not using advanced features and if you like you can keep a C++ program pretty basic.

But it supports all these features to give people what they need to get their jobs done. Lambdas looked a little strange to me at first too but as I studied the examples in Bjarne's book they became clear and I think they are quite expressive, easy to use and worth looking into, especially when you combine them with the types and algorithms in the STL.

Look, I'm a Bjarne fanboy, have been since I started programming in the 90's so maybe my bias is showing through but I never thought I'd come to an article about C++ on /. and find the only comments above a 3 were people whining about how complex a programming language is. Programming is complex, system's programming doubly so and C++ is designed to help reduce that complexity, while at the same time remaining resource efficient, when it's used correctly. If it's too hot to handle for you there is always Visual Basic.

And? Life is a learning experience, so break out the reference manuals and learn something new. Unless you've been thrown in way over your head it's unlikely you'll encounter more than one or two new methodologies in any given codebase, and it'll probably be pretty glaringly obvious when you run into a language feature you don't understand.
