Producer-ProducerConsumer-Consumer-Model

This is a simulation of the model Producer-ProducerConsumer-Consumer. Using semaphores and sharing memory to make processes able to communicate and send messages to each others.
The Producer is the first process, it produces data and send it to ProducerConsumer. ProducerConsumer consume the data send it by Producer then it creates another data and send it to the third process the Consumer.
This model help students to understand communication between processes on Linux OS using programming language C.
