Creational Design Patterns in Modern C++ - Logger Class - Part II

The video tutorial discusses the issues with multiple logger instances corrupting log files and the need to make the constructor private to prevent this. It explains creating a static instance of the logger and the problems with copy constructors leading to shallow copies. The tutorial covers preventing object copies using the delete modifier and the rule of three and five in C++ for managing ownership semantics. It concludes with a brief mention of other methods for creating logger instances.

Why is it suggested to use references instead of pointers when returning instances from the logger class?

What changes are introduced in C++11 regarding the management of resources in classes?

What is the rule of five and how does it relate to the logger class?
