Why Am I Not Getting Errors?

Question

I am trying to compare 3 values that are same.

if(a==b==c)
{
cout<<"what is happening :("
}

And I am not taking any errors. Program is saying that "No Output".

Answer 1

Because
(a==b)==c
Or:
true==c / false==c
is what's tested.
It's false either way, so No Output

Answer 2

He marked a best answer showing he got what he wants

Answer 3

It doesn't!
Let's assume he corrects his syntax and declares a b c

Answer 4

Nevermind $Vengat. I like to take my answer from someone that can understand what I want.
