Creational Design Patterns in Modern C++ - Meyer's Singleton

The video tutorial discusses the challenges of locking in programming, particularly when accessing instance variables outside critical sections. It introduces the Meyers Singleton, a solution for double-check locking, which is thread-safe from C++11 onwards. The tutorial compares eager and lazy instance creation for Singleton classes, advising on when to use each based on thread safety and runtime data needs. The Meyers Singleton is recommended for its thread safety and ease of use.
