#include<stdio.h>
#define N 6
main()
{
    int A[N]={6,5,4,3,2,1};
    int i,j,temp;
    printf("排序前：");
    for(i=0;i<N;i++)
    {
        printf("%3d",A[i]);
    }
    printf("\n");
    for(i=1;i<=N-1;i++)
    {
        for(j=N-1;j>0;j--)
        {
            if(A[N-1]<A[N-2])
            {
                temp=A[N-2];
                A[N-2]=A[N-1];
                A[N-1]=temp;
            }
        }
    }
    printf("排序后：");
    for(i=0;i<N;i++)
    {
        printf("%3d\n",A[i]);
    }
    printf("\n");
}运行后跟想象的不一样。。求教

       if(A[N-1]<A[N-2])<----每次都比较最后两个有用吗?
            {
                temp=A[N-2];
                A[N-2]=A[N-1];
                A[N-1]=temp;
            }

对哦，谢啦
