理论课综合训练成绩扣分0~20，怎么没有输入？
#include
void main()
{
int i;
int sum[i];

typedef struct stu
{
int NO;
int pen;
int integrate;
int robot;
int surf;
}S;

S stu[5];

for(int i=0;i<5;i++)
{
printf("输入学号，笔试成绩，理论课综合训练成绩扣分，机考成绩，上机扣分\n");
scanf("%d %d %d %d %d",&stu[i].NO,&stu[i].pen,&stu[i].integrate,&stu[i].robot,&stu[i].surf);

sum[i]=(stu[i].pen-stu[i].integrate)*(6/10)+(stu[i].robot-stu[i].surf)*(4/10);
if(sum[i]<60)
{
printf("该学员挂科\n");
}
}

for(int i=0;i<5;i++)
{
for(int j=0;j<5-i;j++)
{
if(sum[j]>sum[j+1])
{
int temp;
temp=sum[j];
sum[j]=sum[j+1];
sum[j+1]=temp;
}
}
}
for(int i=0;i<5;i++)
{
printf("%d ",sum[i]);

}
}

盘文件输入
并盘文件输出，
输入输出都没讲清楚。。。
