Effective Modern C++ 英文版 PDF Scott Meyers
Praise for effective Modern c++ So, still interested in C++? You should be! Modern C++(i.e, C++11/C++14) is far more than just a facelift Considering the new features, it seems that it's more a reinvention. Looking for guidelines and assistance Then this book is surely what you are looking for Concerning C++, Scott Meyers was and still is a synonym for accuracy, quality, and delight Gerhard Kreuzer Research and Development Engineer, Siemens AG Finding utmost expertise is hard enough. Finding teaching perfectionism an author's obsession with strategizing and streamlining explanations-is also difficult You know you re in for a treat when you get to find both embodied in the same person Effective Modern C++ is a towering achievement from a consummate technical writer. It layers lucid, meaningful, and well-sequenced clarifications on top of complex and nterconnected topics, all in crisp literary style. You're equally unlikely to find a technical mistake, a dull moment, or a lazy sentence in Effective Modern C++ Andrei alexandrescu Ph. D, Research Scientist, Facebook, and author of Modern C++ design As someone with over two decades of C++ experience, to get the most out of modern C++(both best practices and pitfalls to avoid), I highly recommend getting this book, reading it thoroughly, and referring to it often Ive certainly learned new things going through it Nevin liber Senior Software Engineer, DRW Trading Group Bjarne Stroustrup-the creator of C++-said,C++1l feels like a new language Effective Modern C++ makes us share this same feeling by clearly explaining how everyday programmers can benefit from new features and idioms of C++ll and C++14. Another great Scott Meyers book. Cassio ner FX Quantitative Analyst, Lloyds Banking Group Scott has the knack of boiling technical complexity down to an understandable kernel His Effective C++ books helped to raise the coding style of a previous generation of C++ programmers; the new book seems positioned to do the same for those using modern c++ Roger orr OR/2 Limited, a member of the iso c++ standards committee Effective Modern C++ is a great tool to improve your modern C++ skills. Not only does it teach you how when and where to use modern C++ and be effective, it also explains wh ly Without doubt, Scott's clear and insightful writing, spread over 42 well-thought items, gives programmers a much better understanding of the language -Bart vandewoestyne Research and Development Engineer and C++ enthusiast I love C++, it has been my work vehicle for many decades now. And with the latest raft of features it is even more powerful and expressive than I would have previously imagined. But with all this choice comes the question when and how do i apply these features? As has always been the case, Scott's Effective C++ books are the definitive answer to this question Damien watkins Computation Software Engineering Team Lead, CSIRO Great read for transitioning to modern C++-new C++11/14 language features are described alongside C++98, subject items are easy to reference, and advice summarized at the end of each section Entertaining and useful for both casual and advanced c++ developers Rachel cheng F5 Networks If you're migrating from C++98/03 to C++11/14, you need the eminently practical and clear information Scott provides in Effective Modern C++. If you re already writing C++1l code, you'll probably discover issues with the new features through Scotts thorough discussion of the important new features of the language. Either way, this book is worth your time. Rob stewart Boost Steering Committee member(boost. org) Effective modern ct+ Scott Meye Beng. Cambridge.
