Section Recap

What we learned

You now understand pointers and references.

1.1. Pointers store memory addresses with *

2.2. References create aliases with &

3.3. Pass by reference avoids copying large data

4.4. Dereferencing accesses the value at an address

Good job. You can now work with memory directly. Next, you will learn structs to group related data.
