为何错了？

#include <bits/stdc++.h>
using namespace std;
int main()
{
  int a,b,c;
  cin>>a>>b>>c;
  if(a<b<c)cout<<a<<" "<<b<<" "<<c;
  if(a<c<b)cout<<a<<" "<<c<<" "<<b;
  if(b<a<c)cout<<b<<" "<<a<<" "<<c;
  if(b<c<a)cout<<b<<" "<<c<<" "<<a;
  if(c<b<a)cout<<c<<" "<<b<<" "<<a;
  if(c<a<b)cout<<c<<" "<<a<<" "<<b;

  return 0;
}
