What are the differences between array types in programming?

There are several array types in programming, such as static arrays, dynamic arrays, and associative arrays. Static arrays have a fixed size, while dynamic arrays can grow or shrink as needed. Associative arrays use key-value pairs for indexing.

Can you give me examples of each type?

Sure! A static array example is int arr[5]; in C, a dynamic array example is ArrayList<Integer> list = new ArrayList<>(); in Java, and an associative array example is let obj = {key: 'value'}; in JavaScript.

What are the advantages of using dynamic arrays?

Dynamic arrays are flexible and can adjust their size during runtime, which makes them more efficient for scenarios where the number of elements is unknown at compile time.

Are there any downsides to using associative arrays?

Yes, associative arrays can have slower access times compared to indexed arrays due to the overhead of hashing keys, and they may consume more memory.
