Explanation / Answer

Below is your complete code

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

#define NUM_THREADS 5

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

int main(int argc, char *argv[])
{
   // create an array of thread struct instances with appropriate length
pthread_t threads[NUM_THREADS];

   long t;

int rc;
   for(t=0; t<NUM_THREADS; t++){
       printf("In main: creating thread %Id ", t);
       //start a new thread and call the appropriate routine with. You need to handle errors.
       //args of the routine should be cast as (void *)t

rc= pthread_create(&threads[t],NULL,PrintHello,(void *)t);

if(rc) {

printf("ERROR;Return code from pthread_create() is %d ",rc);

exit(-1);

}
   }
   /* Last thing that main() should do */
   pthread_exit(NULL);
}
