梯子画得不错！

O(∩_∩)O哈哈~
给楼主改的

版主啊xml怎么解析成wordml形式

#include<stdio.h>
#include<string.h>

struct student        /*定义学生信息*/
{
     char num;
     char name[20];
     char sex;
     char major;
     int chinese;
     int math;
     int english;
};
 struct student str[30];
 void com(struct student *score);

void main()
{
    int i;
    for(i=0;i<30;i++)        /*循环录入学生信息*/
    {
    printf("please input the num %d\n",i+1);
    printf("please input the name \n");
    printf("please input the sex\n");
    printf("please input the major\n");
    printf("please input the chinese score\n");
    printf("please input the math score\n");
    printf("please input the english score\n\n");
     scanf("%d\n",&str[i].num);
     scanf("%s\n",&str[i].name);
     scanf("%c\n",&str[i].sex);
     scanf("%s\n",&str[i].major);
     scanf("%d\n",&str[i].chinese);
     scanf("%d\n",&str[i].math);
     scanf("%d\n",&str[i].english);
     printf("\n");
    }

   
    com(str);
}
void com(struct student *score)
{
       int a,b,c,d,e,j;
        a = 0;
        b = 0;
        c = 0;
        d = 0;
        e = 0;
        for(j=0;j<30;j++)
        {
            switch(score[j].chinese / 10)
            {
            case 0:
            case 1:
            case 2:
            case 3:
            case 4:
            case 5:
                e++;
                break;
            case 6:
                d++;
                break;
            case 7:
                c++;
                break;
            case 8:
                b++;
                break;
            case 9:
            case 10:
                a++;
                break;
            default :
                printf("error");
            }
           
        }
         printf("不及格：%d\n,及格：%d\n,中:%d\n,良:%d\n,优:%d\n",e,d,c,b,a);
    }

现在好了
楼主试下

接上面那位兄弟的其实在统计成绩时用switch要不if else好点。

感谢各位了，刚才才吃完饭回家。

chinese应该为str[i].english还有很多定义的major[]

char s[10];
scanf("%s",s);
或
int i=0;
scanf("%d",&i);所以你输入有问题
还有你传的是struct student str[30]的首地址（该地址放在了p中），传值给score，p和score中都只放了一个地址，大小4个字节（一个整型数据），访问
struct student str[30]数组的遍历方法就是score+i->的循环；
switch少大括号
printf语句写在循环外面
