Question

C编程问题，程序出错了，求大神解答，一下是我编写的，请各位大神帮帮忙

#include<stdio.h>
#define M 45
struct student
{int stuno;
char name[20];
float score[3];
float average;
}
void input(struct student s[],int n)
{int i,j;
struct student t;
for(i=1;i<=n;i++)
{scanf("%d%s",&t.stuno,t.name);
for(j=0;j<=2;j++)
scanf("%f",&t.score[j]);
s[i]=t;
}
}
void caculate(struct student s[],int n)
{int i,j;
for(i=0;i<=n;i++)
s[i].average=0;
for(j=0;j<=2;j++)
s[0].score[j]=0;
for(i=1;i<=n;i++)
{for(j=0;j<=2;j++)
{s[i].average+=s[i].score[j];
s[0].score[j]+=s[i].score[j];
}
s[i].average/=3;
}
for(j=0;j<=2;j++)
s[0].score[j]/=n;
}
void output(struct student s[],int n)
{int i,j;
printf("stuno name score[0] score[1] score[2] average\n");
for(i=1;i<=n;i++)
{printf("%-5d%10s",s[i].stuno,s[i].name);
for(i=0;j<=2;j++)
printf("%6.1f",s[i].score[j]);
printf("%6.1f\n",s[i].average);
}
printf("average of total");
for(j=0;j<=2;j++)
printf("%6.1f",s[0].score[j]);
printf("\n");
}
void main()
{struct student stu[M];
int n;
printf("Please input the number of students(1-45)");
scanf("%d",&n);
input(stu,n);
caculate(stu,n);
output(stu,n);
}

Answer 1

struct student
{int stuno;
char name[20];
float score[3];
float average;
}；
加一个分号

请问为什么我运行后会乱码？

追答

你的
void output(struct student s[],int n)
{int i,j;
printf("stuno name score[0] score[1] score[2] average\n");
for(i=1;i<=n;i++)
{printf("%-5d%10s",s[i].stuno,s[i].name);
for(j=0;j<=2;j++)// !!!这里错了
printf("%6.1f",s[i].score[j]);
printf("%6.1f\n",s[i].average);
}
printf("average of total");
for(j=0;j<=2;j++)
printf("%6.1f",s[0].score[j]);
printf("\n");
}

应该怎样改呢？

你仔细看一下，你的是i,应该是j
