不懂你后一句话，不过给数字排列今天我才刚刚学过
下面这个是我用vc++6.0写的 给3个数排列 从大到小
# include <stdio.h>
int main (void)
{
int a, b, c, t; //t是用来互换两个数
printf("请输入三位实数(用空格隔开)\n");
scanf("%d %d %d",&a,&b,&c);
if (a<b)
{
t = a;
a = b;
b = t;
}
if (a<c)
{
t = a;
a = c;
c = t;
}
if (b<c)
{
t = b;
b = c;
c = t;
}
printf("%d %d %d", a, b, c);
return 0;
}
