The new C++ standard

C++ is still vital. It’s changing and getting better. I like it. I wish I could use it more.

I spotted on Esther Schindler’s Twitter feed a link to the Dr. Dobb’s article on the new C++ 14 standard.

This is exciting for me. I really like C++, even though I hardly ever get to use it. It’s a super-sharp power tool that simply isn’t as useful as C# in the database-heavy applications I usually work on. I have a lot of nostalgia wrapped up in C++. I remember running across the Stroustrup book in the public library (of all places!) and being fascinated by the concept and implementation of object orientation.

Sure, a lot of people would say that ruined me, because C++ is far from a purist’s language, but in its era C++ offered a pragmatic solution to a great many typical development challenges.

What’s new in C++

First of all, you know how you can use that var declaration in C# when it was too inconvenient (or at times impossible) to specify the type of a variable? You can do that in C++ 14 and you can specify the return type of a method the same way!

There’s a new [[deprecated]] attribute. It doesn’t break any code, it just kicks out a warning when you try to call anything that you’ve flagged as deprecated. Good way to soften the transition away from an API or implementation.

Syntactic sugar: You can now have digit separators in constants. You can write a million now as 1,000,000 if you want.

Generic lambdas with auto type parameters! That’s kind of esoteric, but the point is being able to declare lambdas that will figure out for themselves at compile time what argument types they need. It makes them more reusable.

Conclusion

C++ is still vital. It’s changing and getting better. I like it. I wish I could use it more.
