What are the best practices for global storage in C++11?

In C++11, it's recommended to minimize the use of global variables. Instead, consider using static local variables or singleton patterns.

Why should I avoid global variables?

Global variables can lead to tight coupling and make your code harder to maintain and test. They can also introduce issues with thread safety.

What alternatives do I have to global variables?

You can use function parameters, class members, or encapsulate data within namespaces to limit the scope and improve modularity.

Can you explain the singleton pattern?

Sure! The singleton pattern ensures a class has only one instance and provides a global point of access to it, often implemented with a private constructor and a static method.
