image The meeting of the ISO WG21 C ++ Committee, which was held in Toronto from 10 to 15 July, ended today. Soon we will surely be waiting for detailed report from WP21 , and today the respected public is offered a post- "Warming up" with a discussion of the most interesting.

The results of the meeting are as follows: C ++ standard 17 is completed and will be published at the next meeting in November this year; the standard C ++ 20 has already acquired the first serious features - concepts ( concepts ), explicit generic lambda functions (explicit explicit lambdas < / i>) - and this is just the beginning.

The possibilities of the new C ++ standard 17 have been discussed more than once, about innovations written on Habr , conducted reports at conferences , so I will not bring them here again. It's no secret that the key feature of this release of C ++ was carrying the most "delicious" options into an uncertain future. Well, now we can say with certainty that many of the long-awaited "features" have moved to C ++ 20. The course taken for the stdlib extension has not gone away, so a much larger and rich set of functions can be expected from C ++ 20.

I would like to begin this article from the fact that now it is 2012. I am saying this, because I often read the code in C++ at my work and for hobby, which was written about 10-20 years ago (and it is actual now), or the code written recently by the people who learned to program in C++ 20 years ago. And after that I got feeling that there was not any progress over the years, as well nothing was changed and developed, and the mammoths still roam on the Earth.

Introduction


The programming specific was very different 20 years ago. The memory and resources of CPU were measured by the bytes and the cycles, many things had not been invented yet, and we had to deal with that situation. But this is not an excuse today to write a code based on these prerequisites. The world is changing now. I can feel it in the water. I can feel it in the ground. We need to keep up with the progress.

Everything that I am going to write further only applies to the programming in C++ and the mainstream-compilers (gcc, Intel, and Microsoft), unfortunately, I have worked less with other programming languages and compilers, so I will not talk much about them. Also, I will only talk about the application programming for desktop OS (trends may differ in the clusters, microprocessors and system programming).
