a XOR b is a^b in C language
A = A xor B B = A xor B A = A xor B in C... A^=B; B^=A; A^=B;

The bitwise XOR operator is ^, or shift 6. The bitwise XOR assignment operator is ^=.
Check the following table: a b c a+b+c a^b^c 0 0 0 0 0 = 0 0 1 1 1 = 0 1 0 1 1 = 0 1 1 1 0 1 0 0 1 1 = 1 0 1 1 0 1 1 0 1 0 1 1 1 1 1 = So they are equal if the number of ones between a, b, and c is zero or an odd number.
a=a^b; b=a^b; a=a^b;
a := a XOR b b := a XOR b a := a XOR b it works, but never use it in real programs do you know why its not used in real program??

They perform bitwise operations like AND (&), OR (|), XOR (^) and NOT (~).

It can be implemented very easily .... Suppose the Binary word is X7X6X5.... X0 then the corresponding Gray code is G7G6G5....G0 where G7=X7 G6=X7 XOR X6 G5=X6 XOR X5 ..... G0=X1 XOR X0 Now implement the above algorithm
full adder is made of x-or gates and gates and inverters.it can also be made of two half adders and one or gate.full adder consists of 3 inputs lines and 2 output lines which can be named as sum(s) and carry(c).it is a combinational circuit. s= a xor b xor c(if inputs are named as a ,b,c) c=ab+bc+ca
yes... xor is derived gate from primary gates
