How do I iterate over arrays in C#?

You can use a for loop, foreach loop, or LINQ to iterate over arrays in C#. Which method would you like to know more about?

Can you explain the foreach loop?

Sure! The foreach loop allows you to iterate through each element in an array without needing to manage the index. Here's an example:

string[] fruits = { "apple", "banana", "cherry" };
foreach (string fruit in fruits) {
    Console.WriteLine(fruit);
}

What if I want to modify the elements while iterating?

If you need to modify elements, it's better to use a for loop. Here's how you can do it:

for (int i = 0; i < fruits.Length; i++) {
    fruits[i] = fruits[i].ToUpper();
}
``` This will change all fruit names to uppercase.

Are there any performance differences between these methods?

Yes, foreach is generally easier to read and less error-prone, but for large arrays, a for loop can be more efficient since it avoids the overhead of enumerators.
