#请问这代码可以怎么写

问题遇到的现象和发生背景

课上遇到的问题

问题相关代码，请勿粘贴截图

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

struct stu{
    int seq;
    int gpa;
    struct stu * next;
};

struct stu * CreateRandList( )
///创建含有N位同学的班级，N是一个大于10的随机数 ，按照同学的序号从小到大排列 
///每位同学的成绩在0~99之间随机生成 
///返回头指针
{
    struct stu *head , *p , *q;
    int sum = 0 , i = 0, N = 0;
    srand((int)time(NULL));
    N = 10 +  rand()%100;
    head = (struct stu *)malloc(sizeof(struct stu ));
    q = head;
    for(i = 0; i < N; i++)
    {
        p = (struct stu *)malloc(sizeof(struct stu ));
        sum = rand()%10 + sum + 1;
        p->seq = sum;
        p->gpa = rand()%100;
        q->next = p;
        q = p;
    }
    q->next = NULL;
    return head;
}

void Award( struct stu *head ) 
///打印出成绩最高的同学的序号，如果有多位同学成绩最高则打印出他们所有人的序号 
{
   
}
int main()
{
    struct stu *head;
    head = CreateRandList( );
    Award( head ) ;
  
}

运行结果及报错内容

我的解答思路和尝试过的方法

我想要达到的结果

可以输出注释所提出的要求

#include<stdio.h>
#include<stdlib.h>
#include<time.h>

struct stu{
    int seq;
    int gpa;
    struct stu * next;
};

///返回头指针
{
    struct stu *head , *p , *q;
    int sum = 0 , i = 0, N = 0;
    srand((int)time(NULL));
    N = 10 +  rand()%100;
    head = (struct stu *)malloc(sizeof(struct stu ));
    q = head;
    for(i = 0; i < N; i++)
    {
        p = (struct stu *)malloc(sizeof(struct stu ));
        sum = rand()%10 + sum + 1;
        p->seq = sum;
        p->gpa = rand()%100;
        q->next = p;
        q = p;
    }
    q->next = NULL;
    return head;
}

void Award( struct stu *head ) 
///打印出成绩最高的同学的序号，如果有多位同学成绩最高则打印出他们所有人的序号 
{

int main()
