looping through arrays

Question

is there a way in which you can loop through arrays in c#?

Answer 1

Of course theres a few ways but the two most common ones:

for (int i = 0; i < arrayName.length; i++) {
Console.WriteLine(arrayName[i]);
}

This one works by looping through numbers 0 (start) -> the arrays length which the i variable stores and then accesses it through [i]. For this example lets say the array is type of int.

foreach (int num in arrayName) {
Console.WriteLine(num);
}

The foreach example does the indexing for you. So every iteration the loop changes the num variable to the value in the array if this was our array: int[] arr = {1, 2, 3}; At our first iteration num would be 1, then 2 and finally 3 then exit the foreach loop.
