# define N 10
#include<stdio.h>
typedef char datatype;

int main()
{
    typedef struct student
    {
        datatype  name[N];
        int   score[N];
    }stu1;
    int i, sum = 0;
    stu1={"fh"};
    for (i = 0; i<N; i++) {
        scanf("%d", &stu1.score[i]);
        sum += stu1.score[i];
    }
    printf("the score of fh is %d", sum);
    return 0;
}

stu1相当于struct student，并不是结构体变量，不能赋值。

那该怎么赋值
？
求教

# define N 10
#include<stdio.h>
typedef char datatype;

int main()
{
    struct student
    {
        datatype  name[N];
        int   score[N];
    }stu1 = { "fh" };//这样才是定义了stu1为变量
    int i, sum = 0;
    for (i = 0; i<N; i++) {
        scanf("%d", &stu1.score[i]);
        sum += stu1.score[i];
    }
    printf("the score of fh is %d", sum);
    return 0;
}
