3Question 3.
What is a critical section in thread programming?
- A part of the program not shared among threads.

- True
- False
Show hintHide hint
Recall the purpose of using locks.
Question 5.
Design a multi-threaded application that increments a shared counter safely using locks. Write the code and explain the synchronization mechanism.
Show hintHide hint
Consider how access to the shared counter is controlled.
Question 6.
Explain how using conditions could enhance a scenario where producer and consumer threads are involved. Implement a conceptual code to demonstrate this.
Show hintHide hint
Reflect on the interactions between producing and consuming threads.
