Effective C++ CheatSheet

Chapter 1: Accustoming Yourself to C++

  • Item 1: View C++ as a federation of languages.
  • Item 2: Prefer consts, enums, and inlines to #defines.
  • Item 3: Use const whenever possible.
  • Item 4: Make sure that objects are initialized before they’re used.

Chapter 2: Constructors, Destructors, and Assignment Operators

  • Item 5: Know what functions C++ silently writes and calls.
  • Item 6: Explicitly disallow the use of compiler-generated functions you do not want.
  • Item 7: Declare destructors virtual in polymorphic base classes.
  • Item 8: Prevent exceptions from leaving destructors.
  • Item 9: Never call virtual functions during construction or destruction.
  • Item 10: Have assignment operators return a reference to *this.
  • Item 11: Handle assignment to self in operator=.
  • Item 12: Copy all parts of an object.

Chapter 3: Resource Management

  • Item 13: Use objects to manage resources.
  • Item 14: Think carefully about copying behavior in resource-managing classes.
  • Item 15: Provide access to raw resources in resource-managing classes.
  • Item 16: Use the same form in corresponding uses of new and delete.
  • Item 17: Store newed objects in smart pointers in standalone statements.

Chapter 4: Designs and Declarations

  • Item 18: Make interfaces easy to use correctly and hard to use incorrectly.
  • Item 19: Treat class design as type design.
  • Item 20: Prefer pass-by-reference-to-const to pass-by-value.
  • Item 21: Don’t try to return a reference when you must return an object.
  • Item 22: Declare data members private.
  • Item 23: Prefer non-member non-friend functions to member functions.
  • Item 24: Declare non-member functions when type conversions should apply to all parameters.
  • Item 25: Consider support for a non-throwing swap.

Chapter 5: Implementations

  • Item 26: Postpone variable definitions as long as possible.
  • Item 27: Minimize casting.
  • Item 28: Avoid returning “handles” to object internals.
  • Item 29: Strive for exception-safe code.
  • Item 30: Understand the ins and outs of inlining.
  • Item 31: Minimize compilation dependencies between files.

Chapter 6: Inheritance and Object-Oriented Design

  • Item 32: Make sure public inheritance models “is-a.”
  • Item 33: Avoid hiding inherited names.
  • Item 34: Differentiate between inheritance of interface and inheritance of implementation.
  • Item 35: Consider alternatives to virtual functions.
  • Item 36: Never redefine an inherited non-virtual function.
  • Item 37: Never redefine a function’s inherited default parameter value.
  • Item 38: Model “has-a” or “is-implemented-in-terms-of” through composition.
  • Item 39: Use private inheritance judiciously.
  • Item 40: Use multiple inheritance judiciously.

Chapter 7: Templates and Generic Programming

  • Item 41: Understand implicit interfaces and compile-time polymorphism.
  • Item 42: Understand the two meanings of typename.
  • Item 43: Know how to access names in templatized base classes.
  • Item 44: Factor parameter-independent code out of templates.
  • Item 45: Use member function templates to accept “all compatible types.”
  • Item 46: Define non-member functions inside templates when type conversions are desired.
  • Item 47: Use traits classes for information about types.
  • Item 48: Be aware of template metaprogramming.

Chapter 8: Customizing new and delete

  • Item 49: Understand the behavior of the new-handler.
  • Item 50: Understand when it makes sense to replace new and delete.
  • Item 51: Adhere to convention when writing new and delete.
  • Item 52: Write placement delete if you write placement new.

Chapter 9: Miscellany

  • Item 53: Pay attention to compiler warnings.
  • Item 54: Familiarize yourself with the standard library, including TR1.
  • Item 55: Familiarize yourself with Boost.
