Introduction 1
Chapter 1: Accustoming Yourself to C   11
Item 1: View C   as a federation of languages. 11
Item 2: Prefer consts, enums, and inlines to #defines. 13

Assignment Operators 34
Item 5: Know what functions C   silently writes and calls. 34
Item 6: Explicitly disallow the use of compiler-generated
functions you do not want. 37
Item 7: Declare destructors virtual in polymorphic
base classes. 40
Item 8: Prevent exceptions from leaving destructors. 44
Item 9: Never call virtual functions during construction or
destruction. 48
Item 10: Have assignment operators return a reference to *this. 52
Item 11: Handle assignment to self in operator=. 53

Item 14: Think carefully about copying behavior in
resource-managing classes. 66

and delete. 73
Item 17: Store newed objects in smart pointers in standalone

Chapter 4: Designs and Declarations 78
Item 18: Make interfaces easy to use correctly and hard to
use incorrectly. 78
Item 19: Treat class design as type design. 84
Item 20: Prefer pass-by-reference-to-const to pass-by-value. 86
Item 21: Don’t try to return a reference when you must
return an object. 90
Item 22: Declare data members private. 94

member functions. 98
Item 24: Declare non-member functions when type
conversions should apply to all parameters. 102

Chapter 5: Implementations 113
Item 26: Postpone variable definitions as long as possible. 113
Item 27: Minimize casting. 116

Item 29: Strive for exception-safe code. 127
Item 30: Understand the ins and outs of inlining. 134
Item 31: Minimize compilation dependencies between files. 140
Chapter 6: Inheritance and Object-Oriented Design 149
Item 32: Make sure public inheritance models “is-a.” 150
Item 33: Avoid hiding inherited names. 156
Item 34: Differentiate between inheritance of interface and
inheritance of implementation. 161

Item 44: Factor parameter-independent code out of templates. 212
Item 45: Use member function templates to accept
“all compatible types.” 218
Item 46: Define non-member functions inside templates
when type conversions are desired. 222
Item 47: Use traits classes for information about types. 226
