Şu sıralar C++ ile ilgileniyorum. Dilin geliştiricisi olan B.Stroustrup'un kitabından bir Advice kısmını paylaşmak istedim
1. When you program, you create a concrete representation of the ideas in your solution to some problem. Let the structure of the program reflect those ideas as directly as possible:
a. If you can think of ‘‘it’’ as a separate idea, make it a class.
b. If you can think of ‘‘it’’ as a separate entity, make it an object of some class.
c. If two classes have a common interface, make that interface an abstract class.
d. If the implementations of two classes have something significant in common, make that commonality a base class.
e. If a class is a container of objects, make it a template.
f. If a functıon implements an algorithm for a container, make it a template functıon implementing the algorithm for a family of containers.
g. If a set of classes, templates, etc., are logically related, place them in a common namespace.
2. When you define either a class that does not implement a mathematical entity like a matrix or a complex number or a lowlevel type such as a linked list:
a. Don’t use global data (use members).
b. Don’t use global functıons.
c. Don’t use public data members.
d. Don’t use friends, except to avoid [a] or [c].
e. Don’t put a ‘‘type field’’ in a class; use virtual functıons.
f. Don’t use inline functıons, except as a significant optimization.
