What are some real-world examples of concurrency issues in software development?

Concurrency issues often arise in multi-threaded applications. A classic example is the "dining philosophers" problem, where multiple threads compete for limited resources.

Can you explain the dining philosophers problem in more detail?

Sure! The dining philosophers problem illustrates synchronization issues. Five philosophers sit at a table with a fork between each pair. They need both forks to eat, leading to potential deadlock if they all pick up one fork simultaneously.

What are some solutions to avoid deadlock in this scenario?

One solution is to impose an ordering on the forks. Philosophers must pick up the lower-numbered fork first, preventing circular wait conditions.

Are there any real-world applications of these concepts?

Yes, similar concurrency control mechanisms are used in databases and operating systems to manage resource access and prevent deadlocks.
