Concept explainers

Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Consider the producer-consumer problem where the producer produces items to be consumed by the consumer. A solution of the problem is to be implemented using threads. The main process will run producer and consumer as two different threads. The producer will put the items it generates into a buffer of length 15. The consumer reads the elements of the buffer to get the items. A solution is given below. Each item produced and consumed are also printed to the screen. Run the program several times and find a sample run when the items produced are not correctly consumed. Explain why the program does not always work correctly.
