这个有错误,谁能帮我改一下下呀,thank you 先

#include <stdio.h> #define M 5 /*设一共有5个学生*/ #define N 6 /*设一个学生有六门课*/ typedef struct { float score[N]; int num; /*学生学号*/ }student; void main() { int i,j,k; float total,sum; student a[M]; for(i=0;i<M;i++) { printf("please input the number of %d student:\n",i); scanf("%d",&a[i].num); printf("please input the i student score:\n",i); for(j=0;j<N;j++) scanf("%f",&a[i].score[j]); printf("\n"); }

for(i=0;i<M;i++) for(j=0;j<N;j++) if(a[i].score[j]<60) {printf("the student's number is:%d\n",a[i].num); printf("his score is:"); for(k=0;k<N;k++) {printf("%d",a[i].score[k]); sum+=a[i].score[k];} printf("the average is:\n",sum/N); } }

#include <stdio.h> #include <string.h>

上面两位改的什么呀？运行了吗？当一个学生有多门课不及格时，输出多次，而且输出成绩全部是0

sum

必须初始化！！！

输入有问题是因为编译器的设计问题，本人在vc6.0中编译通过！

关于编译器的问题请看我的文章
