^ is XOR.

In this case, can be written as:

if(x != y)

which may be easier to understand (if you are unfamiliar with the XOR operator)

^ means XOR:

x ^ y is True if only (x == true && y == false ) || (x == false && y == true).

I don't think your expression is correct. If both are false, `x^y` will return false. Your expression will return true due to right side of the `||`. I think you meant `(x == true && y == false ) || (x == false && y == true)` – Broots Waymb Oct 05 '18 at 16:41
@BrootsWaymb its the logic of Xor . if both are false, `(x== true && y== false)` would be false and also `(x == false && y == true)` be false, and false || false would be false – Ashkan Mobayen Khiabani Oct 05 '18 at 16:44

Umm... what?? If both are false, `(x == false && y == false)` is obviously going to return true... – Broots Waymb Oct 05 '18 at 16:45
@BrootsWaymb I made a mistake in my comment (it was not what I wrote in my answer). I edited it. It is what we have studied in mathematics. I have studied pure mathematics ;) – Ashkan Mobayen Khiabani Oct 05 '18 at 16:46

That mistake also exists in your answer... Run your code with x and y both as false and tell me what you get... Because I get true when it should not for XOR. – Broots Waymb Oct 05 '18 at 16:49
@BrootsWaymb ohhhhh yes I had made a mistake in answer too. Thanks. I corrected it. – Ashkan Mobayen Khiabani Oct 05 '18 at 16:52
it was a really silly mistake – Ashkan Mobayen Khiabani Oct 05 '18 at 16:53
