What are some common mistakes with static variables?

What are some common mistakes with static variables in programming?

Common mistakes include not initializing static variables, misunderstanding their scope, and using them inappropriately in multi-threaded environments.

Can you explain why initializing static variables is important?

Initializing static variables is crucial because uninitialized static variables can lead to undefined behavior, making your program unpredictable.

What issues can arise from using static variables in multi-threaded applications?

In multi-threaded applications, static variables can lead to race conditions if multiple threads access and modify them simultaneously without proper synchronization.

How can I avoid mistakes when using static variables?

To avoid mistakes, always initialize static variables, limit their scope, and use synchronization mechanisms in multi-threaded contexts.
