下面是我的程序
#include <stdio.h>
#include <stdlib.h>

struct stu
{
    char name[20];
    int f;
    char d;
    struct stu *pnext;
};
struct stu* newhear()     //为所有学生姓名和成绩进行初始化
{
    struct stu  *ph, *pn, *pe;
    int c, d;
    printf("请输入学生总人数（不超过50人）：");
    scanf_s("%d", &d, 4);                             //输入学生总人数
    pe = (struct stu*)malloc(sizeof(struct stu));    //为pe分配内存       也是第一个节点                    
    ph = pn = pe;                                    //使第一个学生成为头
    for (c = 0; c < d; c++)
    {
        printf("请输入第%d个学生的姓名\n",c+1);
        scanf_s("%s", pn->name, 20); //输入第一个学生的姓名和成绩
        printf("成绩;\n");
        scanf_s("%d",&pn->f, 4);
        if (c < (d - 1))
        {   
            pe = (struct stu*)malloc(sizeof(struct stu));
            pn->pnext = pe;
            pn = pe;
        }
    }
    pn->pnext = NULL;
    return ph;     //返回链表的开头，便于后面调用
}
double Average(struct stu *pe)
{
    struct stu *pa ;
    pa = pe;
    int a;
    int b;
    for(a = 1,b=0; pa != NULL; a++);
    {
        b = pa->f+b;                           
        pa = pa->pnext;
    }
    b = b / a;
    return b;
}

void garde(struct stu *pe,double a)
{
    struct stu *pg = pe;
    while (pg != NULL)
    {
        if ((a + 10) < pg->f)
            pg->d = 'A';
        if ((pg->f>=(a-10))&& (pg->f<=(a+10)));
            pg->d = 'B';
        if(pg->f<(a-10))
            pg->d = 'C';
        pg = pg->pnext;
    }
}
main()
{
    struct stu *pe;
    double a;
    pe = newhear(); //接受链表的头
    a=Average(pe);    //求平均分数
    garde(pe,a);     //调用打分系统
    system("pause");

}

记得有个段子说某个在网吧工作的清洁阿姨看了某个程序员操作后,说"你这里多了个分号……"

有个类似的一个段子就是说某个程序员下班在大街上掏出手提电脑来改bug,结果一个乞丐走过来,指了指屏幕说"分号,分号!"

哇 当时那感觉……
还是吃瓜去好了~

金庸的武侠片看多了

说的就是段子本身,没有别的,只不过直接直白地说漏了个分号,那会就像对你说下雨出门忘记带伞被雨淋而自己全然不知~
