Like arrays, we can perform an operation for every element in the list using for and foreach loops.

With for loops, make sure to use Count to stay within the bounds of the list.

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

With a foreach loop, the counting is handled for you:

foreach (int number in numbers)
{
   Console.WriteLine(number);
}

Generally, we prefer foreach loops because they require less typing and thus less chance for typos.

If the index is used in the operation — like printing out each index and element together — then we’ll use for loops.
