我将选择排序改为了冒泡排序，只改了这些怎么又不行了呢。

void array(int a[10])
{
       int i,j,temp ;

       for(i=0;i<10;i++)
           for(j=0;j<10-i;j++)
             {
                  if (a[j]>a[j+1])
                   {
                        temp=a[j];
                        a[j]=a[j+1];
                        a[j+1]=temp;
                   }
               }
    for(i=0;i<10;i++)
       printf("the number is:%d\n",a[i]);
}
