呵呵 ，我初学C语言，大家帮忙把这个给编出来：
“从键盘上任意输入三个不相等的整数，按从小到大的顺序输出”
  
  谢谢了！

帮你顶一下  我比你 还菜呀  呵呵

  呵呵  还是等高手来吧！

我试试：
main()
{
   int a,b,c;
   printf("please input 3 different integers:");
   scanf("%d%d%d",&a,&b,&c);
   if(a<b)
     {
       int t;
       t=a;
       a=b;
       b=t;
     }
   if(c>a)
     printf("%d,%d,%d",c,a,b);
  else if(b>c)
    printf("%d,%d,%d",a,b,c);
    else
       printf("%d,%d,%d",a,c,b);     


}

#include<stdio.h>
main()
{
float n,a[3];
int i,j;
for(i=0;i<3;i++)
scanf("%f",&a[i]);
for(j=0;j<2;j++)
for(i=1;i<3;i++)
  if(a[j]>a[i])
    {n=a[j];
    a[j]=a[i];
    a[i]=n;
    }
for(i=0;i<3;i++)
printf("%.f\t",a[i]);
}
你要的无聊作业~~~

可以，我试了一下，你的是从大到小输出，一个道理，谢谢了！

????
怎么会是大到小~~~~

没有啊~~~~
是小到大~~~

#include"stdio.h"
void main()
     {
           int a,b,c,t;
      printf("input 3 numbers!");
          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\n",a,b,c);
}

int main()
{
    int first,second,third;
    int maxn = 0;
    printf("Enter the first integer:");
    scanf("%d",&first);
    printf("\nEnter the second integer:");
    scanf("%d",&second);
    printf("\nEnter the third integer:");
    scanf("%d",&third);
    if(first > second)
    {
        if(first > third)
        {
            if(second > third)
            {
                printf("%d %d %d\n",third,second,first);
            }
            else
                printf("%d %d %d\n",second,third,first);
        }
        else
        {
            printf("%d %d %d\n",second,first,third);
        }
    }
    else
    {
        if(second > third)
        {
            if(first > third)
            {
                printf("%d %d %d\n",third,first,second);
            }
            else
            {
                printf("%d %d %d\n",first,third,second);
            }
        }
        else
        {
            printf("%d %d %d\n",first,second,third);
        }
    }
    return 0;
}

呵呵  你的不是  我说的是你上面那个哥们
