关于C语言链表输出的问题！

问题遇到的现象和发生背景

是教材上的一个题目，要求用链表实现，写了好长时间了写不出来人的麻了。
成绩的排序都解决的，但是题目里要求如果成绩相同则并排输出且输出该成绩的人数
输出这一块真的写不出来。

用代码块功能插入代码，请勿粘贴截图

//定义学生信息结构

#include 
#include 
struct student
{
    int id;
    int score;
    struct student* next;
};
typedef struct student Info;

create(Info* head)
{
    Info* p, * q;
    int id, score;
    int flag = 1, no = 1;
    printf("Input Info\n");
    printf("Enter ID = -1 -> end\n");
    do

        {
            printf("PEOPLE: 1\t");
            printf("%d\n", p->id);
        }
        else

}
我想要达到的结果

output那个函数我不知道怎么写

你缺一个函数
排序后，要从头到尾的遍历一遍，看有没有相同的，有相同的删除next，然后cur++
student里少一个属性，人数，默认1，output的时候如果这个是1就不输出，如果不是1要输出人数

题目要求的是把学号全部输出啊（哭）

修改完善如下，供参考：

#include <stdio.h>
#include <stdlib.h>
struct student
{
    int id;
    int score;
    struct student* next;
};
typedef struct student Info;
void create(Info* head)      //修改
{
    Info* p, * q;
    int id, score;
    int flag = 1, no = 1;
    printf("Input Info\n");
    printf("Enter ID = -1 -> end\n");
    do
    {
        printf("Student %d\n", no);
        no++;
        printf("ID:\t");
        scanf("%d", &id);
        //printf("SOCRE:\t"); 修改
        //scanf("%d", &score);修改
        //如果id输入为-1，则停止创建结点
        if (id == -1){
            flag = 0;
        }
        else{
            printf("SOCRE:\t"); //修改
            scanf("%d", &score);//修改
            p = (Info*)malloc(sizeof(Info));
            p->id = id;
            p->score = score;
            q = head;
            while (q->next != NULL)
            {
                if ((p->score) > (q->next->score))
                {
                    break;
                }
                else
                {
                    q = q->next;
                }
            }
            p->next = q->next;
            q->next = p;
        }
    } while (flag);
}
void output(Info* head)  //修改
{
    Info* p, * prv;
    int i = 0,  k = 1, rank = 1, people = 0;
    p = head->next;
    prv = p;
    while (p != NULL)
    {    
        if (prv == p) {
            printf("NO.%d\t", rank);
            printf("SCORE: %d\t", p->score);
        }
        if (p->score != prv->score) {
            rank++;
            printf("PEOPLE: %d\n", people);

            people = 1;
            printf("NO.%d\t", rank);
            printf("SCORE: %d\t", p->score);
            printf("%d ", p->id);
        }
        else{
            people++;
            printf(people % 10 == 0 ? "%d\n\t\t\t" : "%d ", p->id);//同名次的学号一行最多10个
        }    
        prv = p;
        p = p->next;
    } 
    printf("PEOPLE: %d\n", people);
}
void main()
{
    Info* head;
    head = (Info*)malloc(sizeof(Info));
    head->next = NULL;
    create(head);
    output(head);
}
