编写一个对n个数据从大到小的排序C…

# include "stdio.h"
# define N 3
# define M 4
main()
{  int d[N][M],i,j,k,x;
   float t[N];
   printf("please input:");
   for(i=0;i
    for(j=0;j
     scanf("%d",&d[i][j]);
   jun(d,t);
   for(k=0;k
   for(j=k+1;j
     if(t[j]
      { x=t[k];
        t[k]=t[j];
        t[j]=x;
      }
   printf("结果为:\n");
   for(k=0;k
   printf("_  ",t[k]);
   printf("\n");
}
int jun(int d[N][M],float t[N])
{  int i,j,y,k;
   float sum=0;
   for(i=0;i
    {for(j=0;j
      for(k=j+1;k
        if(d[i][k]
         { y=d[i][k];
            d[i][k]=d[i][j];
            d[i][j]=y;
          }
    sum=0;
    for(j=1;j
    sum+=d[i][j];
    t[i]=sum/(M-2);
   }
}
