Introduction
Threaded programming is a powerful tool for creating efficient and reliable applications. It allows multiple tasks to be executed simultaneously, which can greatly improve the performance of an application. However, it can be difficult to get the desired output from a threaded program. This article will provide some tips on how to get your threaded program to print specific output. It will discuss the importance of thread synchronization, the use of locks and semaphores, and the use of thread-safe data structures. Finally, it will provide some examples of how to use these techniques to get the desired output from your threaded program.
Solution
You can use synchronization techniques such as locks, semaphores, and monitors to ensure that the threads print the desired output in the correct order. Additionally, you can use thread-safe data structures such as queues and stacks to store the output and ensure that the threads access the data in the correct order.
You could do this easily in two ways:
-
Pass a ‘print token’ between the threads using two semaphores: thread 1 prints, signals semaphore A, waits on semaphore B then loops. Thread 2 waits on semaphore A, prints, signals semaphore B and loops.
-
Write in-line, single-threaded code.
