为什么一直报错呢？哪里错了呀？

#include <stdio.h>

int decending(int score[])
{int i;
   int j;
   int sum=0;
   
    for(i=9;i>0;i--)
    {
      for(j=0;j<9;j++) 
      {
          if(score[j]>score[j+1])
          {
          int temp=score[j];
          score[j]=score[j+1];
          score[j+1]=temp;
          }
      }
    }
    printf("the decending order is\n");
    for(i=0;i<10;i++)
    {
        printf("%d",score[i]);
        sum=sum+score[i];
    }
  
    int aver=sum/10;
      printf("\nthe lowest score is %d\n",score[0]);
      printf("the highest score is %d\n",score[9]);
      printf("the average score is %d\n",aver);
      printf("the total score is %d\n", sum);
    return 0;   
}
int main()
{
   
    int score[N]={67,98,75,63,82,79,81,91,66,84};
    decending(score);
    return 0;
}
