要求：输入三个数由小到大排序

#include <stdio.h>

int main(int argc, char *argv[])
{
    int a,b,c,t;
    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)//比较顺序不能变 
     {
         t = b;
         b = c;
         c = t;
     }

     printf("%d %d %d",a,b,c);
    return 0;
}
