多个生产者与多个消费者的实现的c语言代码

这里是AI语言模型，以下是多个生产者与多个消费者的C语言代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

#define BUFFER_SIZE 10
#define PRODUCER_NUM 3
#define CONSUMER_NUM 2

int buffer[BUFFER_SIZE];
int in = , out = , count = ;

pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;
pthread_cond_t not_full = PTHREAD_COND_INITIALIZER;
pthread_cond_t not_empty = PTHREAD_COND_INITIALIZER;

void *producer(void *arg)
{
    int id = *(int *)arg;
    while (1) {
        pthread_mutex_lock(&mutex);
        while (count == BUFFER_SIZE) {
            pthread_cond_wait(&not_full, &mutex);
        }
        buffer[in] = rand() % 100;
        printf("Producer %d produced %d\n", id, buffer[in]);
        in = (in + 1) % BUFFER_SIZE;
        count++;
        pthread_cond_signal(&not_empty);
        pthread_mutex_unlock(&mutex);
        sleep(rand() % 3);
    }
    return NULL;
}

void *consumer(void *arg)
{
    int id = *(int *)arg;
    while (1) {
        pthread_mutex_lock(&mutex);
        while (count == ) {
            pthread_cond_wait(&not_empty, &mutex);
        }
        int data = buffer[out];
        printf("Consumer %d consumed %d\n", id, data);
        out = (out + 1) % BUFFER_SIZE;
        count--;
        pthread_cond_signal(&not_full);
        pthread_mutex_unlock(&mutex);
        sleep(rand() % 3);
    }
    return NULL;
}

int main()
{
    pthread_t producers[PRODUCER_NUM], consumers[CONSUMER_NUM];
    int producer_ids[PRODUCER_NUM], consumer_ids[CONSUMER_NUM];

    for (int i = ; i < PRODUCER_NUM; i++) {
        producer_ids[i] = i;
        pthread_create(&producers[i], NULL, producer, &producer_ids[i]);
    }

    for (int i = ; i < CONSUMER_NUM; i++) {
        consumer_ids[i] = i;
        pthread_create(&consumers[i], NULL, consumer, &consumer_ids[i]);
    }

    for (int i = ; i < PRODUCER_NUM; i++) {
        pthread_join(producers[i], NULL);
    }

    for (int i = ; i < CONSUMER_NUM; i++) {
        pthread_join(consumers[i], NULL);
    }

    return ;
}
