Write a C language Program for the Given Question Using Bounded Buffer Logic.

In this assignment, you will create a process that uses threads to implement a

multiprogramming scenario and provide synchronization between these threads to

ensure data consistency. You will create four threads 2 producers and 2 consumers,

who will have access to a shared circular buffer of size 20. Each item in the buffer

should hold 1 integer. You can use an integer array as your shared buffer. Each of

the producer threads must update a slot in the buffer with values from 1 to 30 (using

a for loop with 30 iterations). Each of the consumer threads must update a shared

variable called SUM by reading the buffer one item at a time. Each consumer can

read any item in the buffer, but only 1 at a time. Each item should be read by exactly

1 consumer. Naturally, each consumer should read the shared buffer only when at

least one slot is full and each producer should write to the shared buffer when at least

one slot is empty.

In summary, you program must have a shared buffer and the shared variable called

SUM. You can create other shared variables as needed. You can use either

semaphores or mutexes to ensure that the threads are synchronized with each other.

After all the producers and consumers have completed the execution, you should

print the value of the shared variable SUM. The value of SUM, if your program is

void of race conditions, should be 930.

Conditions:

1) In Each Producer and Consumer, the following Sections need to be clearly identified: entry, critical, exit, and remainder sections.

2) Explain the code using Comments Clearly.

3) There should be no race cases. All race cases should be ignored. (Marks will be deducted if found any race cases)

4) Explain implementation of Threads, Semaphores, mutex using comments.

5) Explain working of logic using Comments.
