建立鏈表的時候錯了.
head->next?=?NULL;
p2?=?head;
while(1){
????if((p1?=?(Stu*)malloc(sizeof(Stu)))?==?NULL){exit(0);}
????scanf("%d,%s,%f",&p1->ID,p1->name,&p1->score);
????if(p1->ID?==?0){
????????free(p1);
????????break;
????}else{
????????p2->next?=?p1;
????????p1->next?=?NULL;
????????p2?=?p1;
????}???
}
