دانلود کتاب راهنمای جامع ++C

Thank you for purchasing this book! There are always modern features in C++ that enable new ways of working and new idioms. If you ask the internet for examples in C++, most sources lean towards the C-like style, which has little to do with the possibilities of modern C++: resource acquisition is initialization (RAII) up front, new concepts and modules and coroutines and ranges. As always, I intend to show you the strengths of C++ in particular—especially where I believe that C++ is ahead of other languages. In this edition, I am assuming you will use a compiler that is fully capable of C++17. Because all popular compilers now also support C++20, you will have no problems with those features either. In the book, I mostly point out the use of C++20, but at the publisher’s request, I have refrained from specific typographical emphasis on the same. I also describe C++23 features, which I always point out and emphasize, as compiler support for these features is far from complete. I want to briefly draw your attention to C++17 features that I no longer emphasize, but that I use in almost all listings and that could confuse you if your compiler does not handle them. You still need to write the class template argument deduction for constructors in vector data{1,2,3} as vector<int> data{1,2,3}. You will miss string_view and instead need to write const string&. There are a few more little things that I won’t list here. In C++20, abbreviated function templates have been added, which are extremely useful, but sometimes difficult to point out in listings. If you ever see auto in a function parameter, then it is actually a function template. However, there are also gaps: Modules unfortunately are not yet fully developed, so I cannot give you many tips on them. And while format is widely supported, this is not yet the case for print. Of course, there is nothing to be said against writing your program “traditionally.” In short, to me, that means that your program looks more like C than it could look. There’s nothing wrong with that, of course. Some of the best programs are written in C. Nevertheless, if you start a project today and decide to use a programming language translated into machine code, you’d be better off using C++. Because something is happening in the language—or rather, something has happened. With C++23, you have a language that supports you in writing good programs in an up-to-date way. This means that your programs are fast, error resistant, and maintainable. You can program productively.
