What are the advantages of using a list over an array?

Answer from AI
Lists (for example, List<T> in C#) have several advantages over arrays:
-
Dynamic size: Lists automatically resize when adding or removing elements, whereas arrays have a fixed length after creation.
-
Convenient methods: List<T> provides many methods for working with collections — adding, removing, searching, sorting, etc., which simplifies the code.
-
Type safety: List<T> is a generic type that ensures type checking at compile time.
-
Integration with LINQ: Lists are easy to use with LINQ for convenient data processing.
Example of using a list:
List<int> numbers = new List<int>();
numbers.Add(1);
numbers.Add(2);
numbers.Remove(1);
foreach (var num in numbers) {
Console.WriteLine(num);
}
While arrays are suitable for a fixed number of elements and can be slightly more memory-efficient, lists provide greater flexibility and convenience in most scenarios.
