}


这一段好像没有运算,怎么回事?stud[i].average[i]=(stud[i].score[0]+stud[i].score[1]+stud[i].score[2])/3;}

#include<iostream.h>
#include<stdio.h>

struct student
{
int num;
char name[20];
float score[3];
float average[1];
};
void main()
{

student stud[1];
for(int i=0;i<1;i++)

{ cout<<"please enter the number:";
cin>>stud[i].num;
cout<<"please enter the name:";
cin>>stud[i].name;
for(int j=0;j<3;j++)
{cout<<"please enter the score:";
cin>>stud[i].score[j];}
stud[i].average[i]=(stud[i].score[0]+stud[i].score[1]+stud[i].score[2])/3;} //最后面的"}"
printf("name=%s\tscore=%f",stud[i].name,stud[i].score);
printf("average=%.1f",stud[i].average[i]);
//应该放在这里
}

for(int i=0;i<1;i++)结束后i就是1了，而不是0。
所以
printf("name=%s\tscore=%f",stud[i].name,stud[i].score);
printf("average=%.1f",stud[i].average[i]);
都是在print stud[1]，没有crash已经是幸运了。

#include<iostream.h>
#include<stdio.h>

struct student
{
int num;
char name[20];
float score[3];
float average[1];
};
void main()
{

student stud[1];
for(int i=0;i<1;i++)

{
cout<<"please enter the number:";
cin>>stud[i].num;
cout<<"please enter the name:";
cin>>stud[i].name;
for(int j=0;j<3;j++)
{
cout<<"please enter the score:";
cin>>stud[i].score[j];
}
stud[i].average[i]=(stud[i].score[0]+stud[i].score[1]+stud[i].score[2])/3;
}
printf("name=%s\t\nscore=%f\n",stud[0].name,stud[0].score);
printf("average=%.1f",stud[0].average[0]);

}

你的最后输出的时候有错误,此时的i=3了,你又用
printf("name=%s\t\nscore=%f\n",stud[i].name,stud[i].score);
printf("average=%.1f",stud[i].average[i]);
输出,怎么也不可能得到输出的数呀,

楼上的和我的回答实际是一样的.

呵呵~
