When deciding whether to use an array or a list, think about a few important points:
-
Fixed Size vs. Flexible Size:
- Arrays: These have a set size. Once you choose how many items you want to keep, you can’t change it. So, if you know exactly how many things you’ll need, go with arrays.
- Lists: These can grow or shrink in size. This means you can add or take away items whenever you want. Lists are perfect if you’re not sure how many things you will have.
-
Speed:
- Arrays: Usually faster for getting items because they keep everything close together in memory.
- Lists: Might be a little slower because they need to adjust their size and manage pointers inside.
-
When to Use Them:
- Array Example: If you’re keeping track of a set number of scores in a game, an array works well.
- List Example: If you’re gathering user comments that can vary in number, lists are the better choice.
In summary, pick arrays when you need a fixed size and lists when you want more flexibility!
