怎樣修改下面程式,輸入三個數字比大小
比如結果為:1<2<3
            3>2>1
            6<8>1
            8>1<5

#include <stdio.h>
#include <stdlib.h>

int main (void)
{

int a,b,c;

printf("~~~~~~~比大小程式~~~~~~~~\n");
printf("請輸入第一個數字:");
scanf("%d",&a);
printf("請輸入第二個數字:");
scanf("%d",&b);
printf("請輸入第三個數字");
scanf("%d",&c);

if (a > b > c)
   printf("%d > %d > %d\n",a ,b,c);
else if  (a < b < c)
   printf("%d < %d < %d\n",a ,b,c);
else  if (a > b < c)
   printf("%d > %d < %d\n",a ,b,c);
   else
   printf("%d < %d > %d\n",a ,b,c);



printf("\n");
system("pause");
return 0;
}

if (a > b && b > c)
{
printf("%d > %d > %d\n", a, b, c);
}
else if (a < b && b < c)
{
printf("%d < %d < %d\n", a, b, c);
}
else if (a > b && b < c)
{
printf("%d > %d < %d\n", a, b, c);
}
else
printf("%d < %d > %d\n", a, b, c);

   }

char function(int x, int y)
{
if(x==y)
return '=';
if(x>y)
return '>';
return '<';
}
