Answer 1

If you use an array, then the data is initialized at runtime. If you use the pointer, the run-time overhead is (probably) less because only the pointer needs to be initialized. (If the data is smaller than the size of a pointer, then the run-time initialization of the data is less than the initialization of the pointer.) So, if you have enough data that it matters and you care about the run-time cost of the initialization, you should use a pointer. You should almost never care about those details.
