Copied Value

In parallel programming, we can come across situations where different threads need the same resource. This can result in a race condition as the two threads compete for the same resource. To avoid consistency issues, we need to synchronize it. This problem can be solved using OS concepts like mutex locks, but those are not covered in the scope of this course. In this lesson, we’ll learn how the copied value pattern can solve our synchronization problem.

According to the copy value pattern, the thread should receive its data by copy and not by reference.

Let’s take a look at its code.
