Lesson 13 - Templates New

Sometimes we can have an algorithm that is so versatile that it doesn't mind different data types. One such algorithm may be the dynamic array we showed in the last lesson. No matter what types we store, we can store them all in an array and ideally work with them the same way. Another example could be an algorithm for swapping two variables. We used to have a swap function in the series that did exactly that, but only for integers. Again, this is a universal algorithm that we can use for each type.
