Sinopsis

Coming to grips with C++11 and C++14 is more than a matter of familiarizing yourself with the features they introduce (e.g., auto type declarations, move semantics, lambda expressions, and concurrency support). The challenge is learning to use those features effectively-so that your software is correct, efficient, maintainable, and portable. That's where this practical book comes in. It describes how to write truly great software using C++11 and C++14-i.e. using modern C++.

Topics include:

The pros and cons of braced initialization, noexcept specifications, perfect forwarding, and smart pointer make functions
The relationships among std::move, std::forward, rvalue references, and universal references
Techniques for writing clear, correct, effective lambda expressions
How std::atomic differs from volatile, how each should be used, and how they relate to C++´s concurrency API
How best practices in ´old´ C++ programming (i.e., C++98) require revision for software development in modern C++
Effective Modern C++ follows the proven guideline-based, example-driven format of Scott Meyers´ earlier books, but covers entirely new material.



Chapter 1: Deducing Types
Item 1: Understand template type deduction.
Item 2: Understand auto type deduction.
Item 3: Understand decltype.
Item 4: Know how to view deduced types.
Chapter 2: auto
Item 5: Prefer auto to explicit type declarations.
Item 6: Use the explicitly typed initializer idiom when auto deduces undesired types.
Chapter 3: Moving to Modern C++
Item 7: Distinguish between () and {} when creating objects.
Item 8: Prefer nullptr to 0 and NULL.
Item 9: Prefer alias declarations to typedefs.
Item 10: Prefer scoped enums to unscoped enums.
Item 11: Prefer deleted functions to private undefined ones.
Item 12: Declare overriding functions override.
Item 13: Prefer const_iterators to iterators.
Item 14: Declare functions noexcept if they won't emit exceptions.
Item 15: Use constexpr whenever possible.
Item 16: Make const member functions thread safe.
Item 17: Understand special member function generation.
Chapter 4: Smart Pointers
Item 18: Use std::unique_ptr for exclusive-ownership resource management.
Item 19: Use std::shared_ptr for shared-ownership resource management.
Item 20: Use std::weak_ptr for std::shared_ptr-like pointers that can dangle.
Item 21: Prefer std::make_unique and std::make_shared to direct use of new.
Item 22: When using the Pimpl Idiom, define special member functions in the implementation file.
Chapter 5: Rvalue References, Move Semantics, and Perfect Forwarding
Item 23: Understand std::move and std::forward.
Item 24: Distinguish universal references from rvalue references.
Item 25: Use std::move on rvalue references, std::forward on universal references.
Item 26: Avoid overloading on universal references.
Item 27: Familiarize yourself with alternatives to overloading on universal references.
Item 28: Understand reference collapsing.
Item 29: Assume that move operations are not present, not cheap, and not used.
Item 30: Familiarize yourself with perfect forwarding failure cases.
Chapter 7: Lambda Expressions
Item 31: Avoid default capture modes.
Item 32: Use init capture to move objects into closures.
Item 33: Use decltype on auto&& parameters to std::forward them.
Item 34: Prefer lambdas to std::bind.
Chapter 8: The Concurrency API
Item 35: Prefer task-based programming to thread-based.
Item 36: Specify std::launch::async if asynchronicity is essential.
Item 37: Make std::threads unjoinable on all paths.
Item 38: Be aware of varying thread handle destructor behavior.
Item 39: Consider void futures for one-shot event communication.
Item 40: Use std::atomic for concurrency, volatile for special memory.
Chapter 9: Tweaks
Item 41: Consider pass by value for copyable parameters that are cheap to move and always copied.
Item 42: Consider emplacement instead of insertion
