下面是我的代码，但是结果不正确，谁帮忙看下。
#include  <stdio.h>
#define  N 16

typedef struct student
{
    char num[10];
    int s;
} STREC;

void  fun(STREC a[N]);
 
int main()
{
    STREC s[N] = { {"GA005", 85}, {"GA003", 76}, {"GA002", 96}, {"GA004, 85"}, {"GA001, 91"},
    {"GA007, 72"}, {"GA008, 64"}, {"GA006, 87"}, {"GA015, 85"}, {"GA013, 91"}, {"GA012, 64"},
    {"GA014, 91"}, {"GA011", 66}, {"GA017, 64"}, {"GA018, 64"}, {"GA016, 72"} };
     int i;
     FILE * out;
     fun(s);
     printf("The data after sorted:\n");
     for (i = 0; i < N; i++)
     {
         if ((i) % 4 == 0) printf("\n");
         printf("%s%6d", s[i].num, s[i].s);
     }
     printf("\n");
     out = fopen("out.dat", "w");
     for (i = 0; i < N; i++)
     {
         if ( (i) % 4 == 0 && i )  fprintf(out, "\n");
         fprintf(out, "%4d  ", s[i].s);
     }
     fprintf(out, "\n");
     fclose(out);
}

void fun(STREC a[N])
{
      int i , j ; STREC temp;

      for (i = 0; i < N - 1; i++)
      {
          for (j = i + 1; j < N ; j++)
          if (a[i].s < a[j].s )
          {
             temp = a[i];
             a[i] = a[j];
             a[j] = temp;
          }
      }
}

好好看看你的数据双引号加在哪里了
