Put it in C$++.$

Write a Pthreads program that implements a task queue. The main thread begins by starting a user$-$specified number of threads that immediately go to sleep in the condition of waiting. The main thread generates blocks of tasks to be carried out by the other threads; each time it generates a new block of tasks, it awakens a thread with a condition signal. When a thread, finishes executing its block of tasks, it should return to a condition wait. When the main thread completes generating tasks, it sets a global variable indicating that there will be no more tasks and awakens all the threads with a condition broadcast. For the sake of explicitness, make your tasks linked list operations.
