Constructors, Destructors, and Assignment Operators.
Item 12: Prefer initialization to assignment in constructors.

Item 17: Check for assignment to self in operator=.
Classes and Functions: Design and Declaration.
Item 18: Strive for class interfaces that are complete and minimal.
Item 19: Differentiate among member functions, global functions, and friend functions.
Item 20: Avoid data members in the public interface.
Item 21: Use const whenever possible.
Item 22: Pass and return objects byreference instead of by value.
Item 23: Don't try to return a reference when you must return an object.
Item 24: Choose carefully between function overloading and parameter defaulting.
Item 25: Avoid overloading on a pointer and a numerical type.
Item 26: Guard against potential ambiguity.
Item 27: Explicitly disallow use of implicitly generated member functions you don't want.
Item 28: Use structs to partition the global namespace.
Classes and Functions: Implementation.
Item 30: Avoid member functions that return pointers or references to members less accessible than themselves.
Item 31: Never return a reference to a local object or a dereferenced pointer initialized by new within the function.
Item 32: Use enums for integral class constants.
Item 33: Use inlining judiciously.
Item 34: Minimize compilation dependencies between files.
Inheritance and Object-Oriented Design.

Item 49: Plan for coming language features.
Item 50: Read the ARM.
