从键盘上任意输入三个整数a、b和c，按降序形式进行交换，既交换后a最大，b次之，c最小，然后输出a、b和c的值


#include<stdio.h>

int main(void)
{
    int a, b, c, t;

    printf("Input a, b, c:");
    scanf("%d %d %d", &a, &b, &c);
    if (a > b)
    {
        if (b < c)
        {
            if (a > c)
            {
                t = c;
                c = b;
                b = t;
            }
            else
            {
                t = a;
                a = c;
                c = b;
                b = t;
            }
        }
    }
    else
    {
        if (b > c)
        {
            if (a > c)
            {
                t = a;
                a = b;
                b = t;
            }
            else
            {
                t = a;
                a = b;
                b = c;
                c = t;
            }
        }
        else
        {
            t = a;
            a = c;
            c = t;
        }   
    }
    printf("%d  %d  %d\n", a, b, c);
    return 0;
}

四楼说的对

就他了，看的很清晰，3Q!!!

没问题啊  能运行啊
