How could we swap two number(in C language) without using third veriable as well as without using arithematic operators?

Not sure if this helps as it uses arithmetic operators, ... a = a + b b = a - b a = a - b

A less known method using addition and subtraction, limited to integers too: #define SWAP(a, b) ((a) -= (b), (b) += (a), (a) = (b) - (a))
