   printf("学号%d的成绩：%f\n",p->num,p->score);
   p=p->next;
  }while(p);
}
}


//打印内容乱码//
Please enter the num :3
Please enter the score :3
Please enter the num :3
Please enter the score :3
Please enter the num :3
Please enter the score :3
Please enter the num :0
Please enter the score :0
There are 3 records!

学号-842150451的成绩：3.000000
学号3的成绩：3.000000
学号3的成绩：3.000000

scanf("%d,&p1->num");


应该是这里有问题 把&p1->num放到双引号外面 scanf("%d",&p1->num);
