The Producer-Consumer problem is a classic problem this is used for multi-process synchronization i.e. synchronization between more than one processes. In the producer-consumer problem, there is one Producer that is producing something and there is one Consumer that is consuming the products produced by the Producer.
Why is producer-consumer problem?
A producer can produce an item and can place in the buffer. A consumer can pick items and can consume them. We need to ensure that when a producer is placing an item in the buffer, then at the same time consumer should not consume any item. In this problem, buffer is the critical section.

When buffer is empty producer can?
“in” used in a producer code represent the next empty buffer. “out” used in consumer code represent first filled buffer. count keeps the count number of elements in the buffer. count is further divided into 3 lines code represented in the block in both the producer and consumer code.Which is a producer?
Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar.

Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment.

Can producer and consumer processes access the shared memory concurrently?
A producer process produces information that is consumed by a consumer process. One solution to the producer-consumer problem uses shared memory. To allow producer and consumer processes to run concurrently, we must have available a buffer of items that can be filled by the producer and emptied by the consumer.
