补充整个程序

#include<stdio.h>
#define SIZE 300
typedef struct student

    int num;
    double score[3];

{
    False,True
}FLAG;
int main()
{   
    STUDENT stu[SIZE];
    int grade[SIZE]={0};
    int sum;
    int accept(STUDENT stu[],int grade[]);
       sum=accept(stu,grade);
    return 0;
}
int accept(STUDENT stu[],int grade[])
{
    int i=0,sum=0,temp,a1,a2;
    FLAG flag;
    printf("请输入计算总评成绩的平时成绩和考试成绩的比例，用整数表示");
    flag=True;
    while(flag==True)
    {
        scanf("%d,%d",&a1,&a2);
        if((a1+a2)!=100)
            printf("输入数据有错，请输入两个和为100的整数\n");
        else
            flag=False;
    }
    while(i<SIZE)
    {
        printf("请输入学号:");
        scanf("%d",&stu[i].num);
        if(stu[i].num==-1)
        {
            sum=i;
            break;
        }
        printf("请输入学生的平时成绩和考试成绩：");
        flag=True;
        while(flag==True)
        {
            scanf("%d,%d",&stu[i].score[0],&stu[i].score[1]);
            if(stu[i].score[0]>=0 && stu[i].score[0]<=100 && stu[i].score[1]>=0 && stu[i].score[1]<=100)
                flag=False;
            else
                printf("输入的数据有误，请输入0-100的数:");
        }
        temp=(int)(a1/100*stu[i].score[0]+a2/100*stu[i].score[1]);
        stu[i].score[2]=temp;
        temp=(int)stu[i].score[1]/10;
        if(temp==10)
            grade[10]++;
        else
            grade[temp+1]++;
        i++;
    }
    return sum;
}

可以帮我调一下吗，老是说输入数据有误，谢谢
