如何输出动态链表里的每个节点的内容或者输出制定某个节点的内容？

Question

#include <stdio.h>#include <malloc.h>//一共有五位同学 A B C D E F G,编号分别为 1 2 3 4 5 分数 随意 struct std{ char name[3]; float num; float score1; float score2; float score3; float score4; float score5; float addScore; float meanScore; struct std *next;};struct std *create(){ struct std *head; struct std *p1,*p2; int n=0; p1=p2=(struct std*)malloc(sizeof(struct std)); printf("请输入学生名字，编号及各项科目分数：\n"); scanf("%c,%d,%d,%d,%d,%d,%d",&p1->name,&p1->num,&p1->score1,&p1->score2,&p1->score3,&p1->score4,&p1->score5); p1->addScore=p1->score1+p1->score2+p1->score3+p1->score4+p1->score5; p1->meanScore=(p1->score1+p1->score2+p1->score3+p1->score4+p1->score5)/5; head=NULL; while(p1->name!=0){  n++;  if(n==0) head=p1;  else p2->next=p1;  p2=p1;  p1=(struct std*)malloc(sizeof(struct std));  scanf("%c,%d,%d,%d,%d,%d,%d",&p1->name,&p1->num,&p1->score1,&p1->score2,&p1->score3,&p1->score4,&p1->score5);  p1->addScore=p1->score1+p1->score2+p1->score3+p1->score4+p1->score5;     p1->meanScore=(p1->score1+p1->score2+p1->score3+p1->score4+p1->score5)/5;  } p2->next=NULL; return (head);}int main(){  struct std *std_1; std_1= create(); printf("%c,%d,%d,%d,%d,%d,%d,%d",std_1->name,std_1->num,std_1->score1,std_1->score2,std_1->score3,std_1->score4,std_1->score5,std_1->addScore,std_1->meanScore); return 0; }
