c++多线程编程的写法代码

很高兴回答你的问题！以下是一个简单的多线程编程的写法代码示例：

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

#define NUM_THREADS 5

void *PrintHello(void *threadid) {
  long tid;
  tid = (long)threadid;
  printf("Hello World! It's me, thread #%ld!\n", tid);
  pthread_exit(NULL);
}

int main(int argc, char *argv[]) {
  pthread_t threads[NUM_THREADS];
  int rc;
  long t;
  for (t = 0; t < NUM_THREADS; t++) {
    printf("In main: creating thread %ld\n", t);
    rc = pthread_create(&threads[t], NULL, PrintHello, (void *)t);
    if (rc) {
      printf("ERROR; return code from pthread_create() is %d\n", rc);
      exit(-1);
    }
  }
  /* Last thing that main() should do */
  pthread_exit(NULL);
}

希望这个示例代码能够帮助你！
