可以将代码转换成c语音吗

当然可以,以下是基于C语言的实现:
``` c
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
#include <semaphore.h>
#include <unistd.h>
#include <time.h>
#define BUFFER_SIZE 10
int buffer[BUFFER_SIZE];
int in = 0, out = 0;
// 信号量
sem_t mutex, empty, full;
// 生产者
void *producer(void *arg) {
while (1) {
int product = rand() % 100 + 1;
sleep(rand() % 3);
sem_wait(&empty);
sem_wait(&mutex);
buffer[in] = product;
printf("Producer %d produced %d in buffer %d\n", *(int*)arg, product, in);
in = (in + 1) % BUFFER_SIZE;
sem_post(&mutex);
sem_post(&full);
}
}
// 消费者
void *consumer(void *arg) {
while (1) {
sleep(rand() % 3);
sem_wait(&full);
sem_wait(&mutex);
int product = buffer[out];
printf("Consumer %d consumed %d in buffer %d\n", *(int*)arg, product, out);
out = (out + 1) % BUFFER_SIZE;
sem_post(&mutex);
sem_post(&empty);
}
}
int main() {
srand(time(NULL));
pthread_t p[5], c[5];
int i, id[5];
sem_init(&mutex, 0, 1);
sem_init(&empty, 0, BUFFER_SIZE);
sem_init(&full, 0, 0);
for (i = 0; i < 5; i++) {
id[i] = i + 1;
pthread_create(&p[i], NULL, producer, &id[i]);
pthread_create(&c[i], NULL, consumer, &id[i]);
}
for (i = 0; i < 5; i++) {
pthread_join(p[i], NULL);
pthread_join(c[i], NULL);
}
sem_destroy(&mutex);
sem_destroy(&empty);
sem_destroy(&full);
return 0;
}
```
运行结果类似于:
```
Producer 1 produced 5 in buffer 0
Consumer 2 consumed 5 in buffer 0
Producer 2 produced 68 in buffer 1
Consumer 3 consumed 68 in buffer 1
Producer 3 produced 80 in buffer 2
Consumer 4 consumed 80 in buffer 2
Producer 4 produced 25 in buffer 3
Consumer 5 consumed 25 in buffer 3
Producer 5 produced 90 in buffer 4
Consumer 1 consumed 90 in buffer 4
Producer 1 produced 72 in buffer 5
Consumer 2 consumed 72 in buffer 5
Producer 2 produced 60 in buffer 6
Consumer 3 consumed 60 in buffer 6
Producer 3 produced 11 in buffer 7
Consumer 4 consumed 11 in buffer 7
Producer 4 produced 14 in buffer 8
Consumer 5 consumed 14 in buffer 8
Producer 5 produced 84 in buffer 9
Consumer 1 consumed 84 in buffer 9
```
其中,`sem_wait()`和`sem_post()`函数用于对信号量进行等待和释放操作,`sem_init()`用于初始化信号量,`sem_destroy()`用于销毁信号量。在生产者和消费者线程中,都会不断地使用信号量来进行同步控制。
