0==0 means what?

Question

if I write cout<<0==0;
then it gives the output as 0.

why and how?
please explain.

Answer 1

you need brackets. What you are doing now is comparing (cout<<0) with 0

Answer 2

This is because == has a lower operator precedence than <<.

The compiler sees this as:
cout <<0; 0==0;
So 0 is output and then 0==0 is evaluated to true, but nothing is done with it.
