In this case, we've declared something called int arrInts.…So, the square brackets at the end of this tells us that…we're creating something called an array, which is one type of a collection.…We've given it a name called arrInts and we have…assigned some values, 3, 5, 6, 23, 95, 45, 32.…So we throw in some values into this array.…An array is just simply a in-memory representation or a…collection of specific values and in this case, integer values.…I've created that because I wanted you to see how the foreach loop works.…
Up here we simply counted up to ten or up…to nine, because we did less than ten up here.…In this case, we actually have a collection…of values that we're going to iterate over.…So, that's key.…When you think about foreach, think about iteration.…Within our foreach parentheses, we say foreach, int item.…So I've declared a data type of integer called int.…I've given it a name called item.…And I said, for each integer item that's in my array int.…
So, within this integer array, I want you to do a Comsole.WriteLine item.…
