b. The second four should request entrance to their critical sections that is controlled through semaphores, read the values written in the array, and write it to the screen with the following format: "Consumer number - consumed item number-with the value -" And to a file named "Consumer activity", then exit the critical section, and repeat till the producers stop production. The total number of elements generated by the producer and consumed by the consumers should be 10,000,000 number
