Appendix A. Todo

• exceptions <> return values
• when to return a pointer, a value or a reference from a method
• indenting of variable declarations
• unit testing
• no magic numbers
• tabs/spaces policy
• how to break lines
• don't mix pointers and non-pointers on a single declaration line
• use 0 instead of NULL
• #define <> const <> template functions
• match new ~ delete and new[] ~ delete[], don't use malloc ~ free (initialization, destruction, not overloadable)
• base classes virtual destructor
• assignment to self in operator=
• cont correctness and pointers, uses of mutable
• postponed variable declaration at beginning of relevant code block
• public inheritance : isa, layering/composition : hasa is-implemented-in-terms-of, pure virtual function : interface inheritance, simple virtual function : interface inheritance with default implementation (dangerous : sever connection with pure virtual function and explicit default implementation), non virtual function : interface inheritance + mandatory implementation, private inheritance : is-implemented-in-terms-of + implementation inheritance not interface, default parameters and virtual function.
• say what you mean, mean what you say
• inheritance (type of objects changes behaviour) <> templates (type of objects doesn't change behaviour of methods)
