The Singleton Pattern in C++: One Instance, Global Access, Zero Chaos
This tutorial builds a game server logger and a database connection pool to demonstrate the C++ Singleton pattern from the ground up. It covers the private constructor approach, the Meyers singleton with a function-local static, deleting copy and move operations, controlled initialization with a separate init() function, and honest guidance on where the pattern is appropriate versus where dependency injection is the better choice.
