  4. Introduction
    1. Terminology and Conventions
    2. Reporting Bugs and Suggesting Improvements
  5. 1. Deducing Types
    1. Item 1: Understand template type deduction.
      1. Case 1: ParamType is a Reference or Pointer, but not a Universal Reference
      2. Case 2: ParamType is a Universal Reference
      3. Case 3: ParamType is Neither a Pointer nor a Reference
      4. Array Arguments
      5. Function Arguments
    2. Item 2: Understand auto type deduction.
    3. Item 3: Understand decltype.
    4. Item 4: Know how to view deduced types.
      1. IDE Editors
      2. Compiler Diagnostics
      3. Runtime Output
  6. 2. auto
    1. Item 5: Prefer auto to explicit type declarations.
    2. Item 6: Use the explicitly typed initializer idiom when auto deduces undesired types.
  7. 3. Moving to Modern C++
    1. Item 7: Distinguish between () and {} when creating objects.
    2. Item 8: Prefer nullptr to 0 and NULL.
    3. Item 9: Prefer alias declarations to typedefs.
    4. Item 10: Prefer scoped enums to unscoped enums.
    5. Item 11: Prefer deleted functions to private undefined ones.
    6. Item 12: Declare overriding functions override.
    7. Item 13: Prefer const_iterators to iterators.
    8. Item 14: Declare functions noexcept if they won’t emit exceptions.
    9. Item 15: Use constexpr whenever possible.
    10. Item 16: Make const member functions thread safe.
    11. Item 17: Understand special member function generation.
  8. 4. Smart Pointers
    1. Item 18: Use std::unique_ptr for exclusive-ownership resource management.
    2. Item 19: Use std::shared_ptr for shared-ownership resource management.
    3. Item 20: Use std::weak_ptr for std::shared_ptr-like pointers that can dangle.
    4. Item 21: Prefer std::make_unique and std::make_shared to direct use of new.
    5. Item 22: When using the Pimpl Idiom, define special member functions in the implementation file.
  9. 5. Rvalue References, Move Semantics, and Perfect Forwarding
    1. Item 23: Understand std::move and std::forward.
    2. Item 24: Distinguish universal references from rvalue references.
    3. Item 25: Use std::move on rvalue references, std::forward on universal references.
    4. Item 26: Avoid overloading on universal references.
    5. Item 27: Familiarize yourself with alternatives to overloading on universal references.
      1. Abandon overloading
      2. Pass by const T&
      3. Pass by value
      4. Use Tag dispatch
      5. Constraining templates that take universal references
      6. Trade-offs
    6. Item 28: Understand reference collapsing.
    7. Item 29: Assume that move operations are not present, not cheap, and not used.
    8. Item 30: Familiarize yourself with perfect forwarding failure cases.
      1. Braced initializers
      2. 0 or NULL as null pointers
      3. Declaration-only integral static const and constexpr data members
      4. Overloaded function names and template names
      5. Bitfields
      6. Upshot
  10. 6. Lambda Expressions
    1. Item 31: Avoid default capture modes.
    2. Item 32: Use init capture to move objects into closures.
    3. Item 33: Use decltype on auto&& parameters to std::forward them.
    4. Item 34: Prefer lambdas to std::bind.
  11. 7. The Concurrency API
    1. Item 35: Prefer task-based programming to thread-based.
    2. Item 36: Specify std::launch::async if asynchronicity is essential.
    3. Item 37: Make std::threads unjoinable on all paths.
    4. Item 38: Be aware of varying thread handle destructor behavior.
    5. Item 39: Consider void futures for one-shot event communication.
    6. Item 40: Use std::atomic for concurrency, volatile for special memory.
  12. 8. Tweaks
    1. Item 41: Consider pass by value for copyable parameters that are cheap to move and always copied.
    2. Item 42: Consider emplacement instead of insertion.
