Write a C program that solves the producer-consumer problem using condition variables. You may use the following pseudo-code for implementation.

not C++

//Producer thread

do {

produce next item

lock(mutex);

while (buffer is full)

condV.wait(empty, mutex);

add the item to buffer

condV.signal(full);

unlock(mutex);

} while (1);

//Consumer thread

do {

lock(mutex)

while (buffer is empty)

condV.wait(full, mutex)

remove next item from buffer

condV.signal(empty);

unlock(mutex);

consume the item

} while (1);
