1. Briefly explain the difference between pre-incrementing and post-incrementing a numeric variable. (Ex. i++ versus ++i)

2. Why is converting a value of a smaller type to a value of a larger type (i.e., a "widening" conversion) considered "safer" than the converse (a "narrowing" conversion)?

3. If we know that boolean A is false but do not know if boolean B is true or false, then:

We do know A && B is false...

...but we do not know whether B || A is true or false.

Please briefly explain why this is so:

4. Which of the three types of loops (while, do-while, and for) is best suited for working with arrays?
