What does ^ operator do in c++?

Question

and if any library should we include to use this operator?

Answer 1

@WINTER
^ is the XOR operator in C++, just like @Dennis explained. It calculates powers only in a calculator.

But, if you want to use it to calculate powers, you must overload it...

Answer 2

It's the bitwise exclusive operator, or XOR.

Bits that are the same become 0, bits that are not the same become 1

15 = 1111
6 = 110
_________
9 = 1001

Answer 3

is any shortcut technique to do that like other bitwise operators have

Answer 4

cout << ( 15 ^ 6 ) << endl; //XOR, 9
cout << ( 15 | 6 ) << endl; //Or, 15
cout << ( 15 & 6 ) << endl; //And, 6
