Introduction

 

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.  

2. auto  

 

Item 5: Prefer auto to explicit type declarations.  
Item 6: Use the explicitly typed initializer idiom when auto deduces undesired types. 

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.  

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. 

 

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. 

6. 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.  

7. 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. 

8. 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.
