Question

using only bitwise operators (|, &, ~, ^, >>, <<), is it possible to replace the != below?

// ...
if(a != b){
    // Some code
}
/// ...

this is mainly out of self interest, since I saw how to do it with == but not !=.

Answer 1

if(a ^ b) {
    //some code
}

should work.

You can also use your preferred method for == and add ^ 0xFFFFFFFF behind it (with the right amount of Fs to match the length of the datatype). This negates the value (same as ! in front of it).
