When should I use 1D arrays instead of 2D arrays?

When should I use 1D arrays instead of 2D arrays?

1D arrays are best for linear data, while 2D arrays are ideal for tabular data. What specific use case do you have in mind?

I'm working on a game that needs to store player scores. Should I use a 1D or 2D array?

For player scores, a 1D array is sufficient if you only need to store one score per player. If you need to store multiple scores or attributes per player, consider a 2D array.

What if I need to store scores for multiple levels for each player?

In that case, a 2D array would be more appropriate. You can use one dimension for players and the other for levels.

Can you give me an example of how to implement that?

Sure! You can declare a 2D array like this: int scores[NUM_PLAYERS][NUM_LEVELS]; and then access scores using scores[player][level].
