例如有一个结构体数组如下：

struct Student
{
    int num;        //学号
    int chengji[4]; //四科成绩
}

int main(void)
{
    int len, t, i;
    struct Student * p;
    p = (struct Student *) malloc (len * sizeof(struct Student));

    //输入数据
    for(i=0; i<len; i++)
    {
        printf("请输入第 %d 个学生的信息：\n", i+1);
        printf("学号：");
        scanf("%d", &p[i].num);
        printf("姓名：");
        scanf("%s", p[i].name);

        for (t=0; t<4; t++)
        {
            printf("第 %d 科成绩：", t+1);
            scanf("%f", p[i].score+t);
        }
       
    }


    //输出数据
    for(i=0; i<len; i++)
    {
        printf("第 %d 个学生的信息：\n", i+1);
        printf("学号： %d ", p[i].num);
        printf("姓名： %s" , p[i].name);

        for (t=0; t<4; t++)
        {
            printf("第 %d 科成绩： %f", t+1, *(p[i].score)[t]);//有错误
        }
    } 



    return 0;

}

为何 *(p[i+t].score)); 不能输出 score 数组的四个值呢？

    }
    free(p);                                                                                                      
    return 0;                                                                                                     
                                                                                                                  
}                  

首先 你定义的数组是整型 输入的确是浮点型 姓名还没定义呢 错误太多了

呃。在VC上拷过来后想把问题问得精简一些。。。减多了。。。把结构体里面的姓名和学号删了却忘把下边的姓名删了。。。。


谢谢二楼和三楼的同僚。
