tricky code

[kaidranzer]

consider this one its one good tricky code i encountered :

#include <iostream>
using namespace std;

int main()
{
cout << cout;
return 0;
}

any guesses what would be the output ?

[z05DSL3A]

It will output the address of the << operator of cout. (I think :0) )

[kaidranzer]

actually it would output the address of object cout of the class ostream

[z05DSL3A]

I don't think it is the address of the cout object...

It is implementation defined.

It calls basic_ios::operator void*(), which is the function that
gets called when you do something like

if( cin ) {
  // do stuff
}

the function has to return non-zero if the stream is OK or zero otherwise.
