Answer 1

The main difference is that in an expression a && b, b will not be evaluated if a is false, while in a & b both a and b will be evaluated no matter what. One can say that && “short-circuits” the evaluation.

Similarly for a || b: b will not be evaluated if a is true, while in a | b both a and b will be evaluated no matter what.
