Bit shift c code

WebAug 13, 2013 · This means that the user is taking the bits value of 1 and shifting the bits to the left based on the right number. That means that in this case, their values will look like this in binary. 1 << 0 = `0000 0001` 1 << 1 = `0000 0010` 1 << 2 = `0000 0100`. The first shift is not necessary, but it looks more consistent with the rest.
