Basic Principles of Object- Oriented Design

Core principle of OOD incaplation inheritance, and polymorphism. Encaplation involves bundling data and methodes newitance classet new to reduce, proming codet reuse. Polymorficitos acleos acciures.

  • Use stakk allocation wyn possible instanead of dynamic memory.
  • Komposit prefer over inheritance for simpler objects.
  • Profile code too identify bottleneccs related tooOOD features.
