Shell Programming and Scripting

Write a C program that accepts 3 parameters. Each parameter indicates the quantity of product to be
produced. Each product will be produced in different production line. Ready products will be placed
in a buffer area located at the end of each production line. Packaging workers will pack the products
into boxes. Information of each production line as follow:
Production line A: product ready in 1-2 minutes, buffer capacity: 12 units
Production line B: product ready in 2-3 minutes, buffer capacity: 6 units
Production line C: product ready in 1-2 minutes, buffer capacity: 24 units
There are currently 2 packaging workers available. Each worker needs 2 minutes to pack 6 units of
product into a box. The production line will be temporary suspended if the buffer area is full of
product. The operation will continue when the worker has taken 1 unit of product from the buffer
area.
Simulate the operation of production line and the packaging workers by using threads and
appropriate semaphores. There are at least 5 threads, but you may use additional thread if it is
necessary. You have to decide how the workers select the product to pack. Assume that 1 second in
your program is equivalent to 1 minute.
Sample output:

...
Buffer A: 11
Buffer C: 4
Worker X packing B: 3
Buffer B: 8
Worker Y packing C: 2
Buffer A: 12
Production line A suspended.
