I have to implement a solution to the sleeping barber problem using semaphores in Nachos.

The problem I have is that I dont know how to implement an unknown number of semphores in c++. Because the user inputs the number of customers for the barber. And I have to fork that number of threads.
Thanks for all ur help

The semaphores will have to be dynamically alocated with "new".  You can allocate a single array of them if you "learn" the number of customers at the start of the program.  Or if the number of customers constantly changes, you can create a linked list or other container to store them.

Let me knoe if you have questions.
