＃C语言二级考试菜鸡试水
请各位大佬帮忙看下，程序运行完毕后出现乱码，百度上说可能是数组越界？但是我不会改了😭，求指点。放程序和结果:
(fun函数是需要自己编写的部分)
#include <stdio.h>
#define N 12
typedef struct
{ char num[10];
double s;
} STREC;
double fun( STREC *a, STREC *b, int *n )
{
double ave = 0.0,sum=0.0;int i;
for(i=0;i<N;i++)
sum += a[i].s;
ave = (double)sum/N;
*n = 0;
for(i=0;i<N;i++)
{
if(a[i].s>=ave)
{
b[i] = a[i];
(*n)++;
}
}
return ave;
}
main()
{ STREC s[N]={{"GA05",85},{"GA03",76},{"GA02",69},{"GA04",85}****,
{"GA01",91},{"GA07",72},{"GA08",64},{"GA06",87},
{"GA09",60},{"GA11",79},{"GA12",73},{"GA10",90}};
STREC h[N],t;FILE *out ;
int i,j,n; double ave;
ave=fun( s,h,&n );
printf("The %d student data which is higher than %7.3f:\n",n,ave);
for(i=0;i<n; i++)
printf("%s %4.1f\n",h[i].num,h[i].s);
printf("\n");
out = fopen("C:\WEXAM\000000000000\out.dat","w") ;
fprintf(out, "%d\n%7.3f\n", n, ave);
for(i=0;i<n-1;i++)
for(j=i+1;j<n;j++)
if(h[i].s<h[j].s) {t=h[i] ;h[i]=h[j]; h[j]=t;}
for(i=0;i<n; i++)
fprintf(out,"%4.1f\n",h[i].s);
fclose(out);
getchar();
}
还有主函数中，STREC h[N],t;中的t是什么意思呢？谢谢各位大佬！
