I don't know if the error is from C++ compiler or language.

Try this two codes: I tried to compare two string "a" and "adnan", in two codes, it giving me two different outputs, where the second one is correct.

#include<bits/stdc++.h>
using namespace std;

int main()
{
  //  cout<<("a">"adnan")<<endl;
   cout<<("a"> "adnan" ? "a": "adnan")<<endl;

}
/* The output is: 
a

which is incorrect.
*/

and

#include<bits/stdc++.h>
using namespace std;

int main()
{
   cout<<("a">"adnan")<<endl;
   cout<<("a"> "adnan" ? "a": "adnan")<<endl;


}
/* the output is:
0
adnan
*/

which is correct.

I tried from different compilers I've tested it from codechef's compiler also: c++ 14, from ideone: C++, C++ 14

And found the same error. Hope it'll be seen by the C++ language
