+However, **this doesn't mean that you don't need to understand pointers**,

+Pointers are used for strings, arrays that are not fixed-size,
+instances of most classes, and so on.
+
+Basically, you need pointers whenever you want to use a large object in multiple places
+without making several copies of it.
+Instead, you just make one object and point to it from many places.
+This is probably what you expect if you have mostly used high-level languages,
+like Python or JavaScript.
+In fact, in Python, **all** objects are passed around as pointers.
+
+You usually don't need pointers for small objects.
+For example, if you want to make a function takes two `int`s and prints them,
+just make a function that takes two `int`s.
+On the other hand, if your function takes an array of 100000 `int`s,
+you should use a pointer.
+Passing around hundreds or thousands of bytes without pointers is usually a bad idea.
