These are some rules for effective C++ programming. These are taken from
Scott Meyers, and is presented in their short form. These are not all the
rules Meyers presents, only the most important of them. LyX does not yet
follow these rules, but they should be the goal.
- Use const and inline instead of #define
- Use the same form in corresponding calls to new and delete,
i.e. write delete[] obj; if new obj[n]; was used to create
the object and write delete obj; if you wrote new obj;
Notice strings should be LString's instead of char *'s.
- Define a copy constructor and an assignment operator for all
classes with dynamically allocated memory.
- make destructors virtual in base classes.
- assign to all data members in operator=.
- strive for class interfaces that are complete and minimal
- differentiate among member functions, global functions and friend
functions.
- avoid data members in the public interface.
- use const whenever possible
- pass and return objects by reference instead of by value
- choose carefully between function overloading and
parameter defaulting.
- never return a reference to a local object or a dereferenced
pointer initialized by new within the function.
- use enums for integral constants.
- minimize compilation dependencies between files.
- pay attention to compiler warnings
- differentiate between inheritance of interface and
inheritance of implementation.
- differentiate between inheritance and templates
- know what functions C++ silently writes and calls.
- ensure that global objects are initialized before they are used.

==================================
And one of mine: (Lgb)
- When swiching on enums, refrain from using "default:" if possible.
