(To write test cases to make sure the code does what it’s supposed to do.) A fun exercise was also overloading all the functions in order to play nice with all other types. (In order to do “s/string/MyString/” in relatively big code bases and hope stuff still works.)

Beyond that, I also liked learning and doing linked list implementation, but also making sure I don’t have any remaining null pointer references. (segfault, anyone?) Then after getting that down, make it templated. That’s fun. (Tip: `typename Foo::Bar` before functions means you can actually return a type that is a sub-class of another. Without `typename`, g++ barks at you.) After that, stop using pointers directly but instead learned boost’s shared_ptr semantics. Really different method compared to regular ol’ pointers, but I think my code is safer for using them. (At least they clean up after themselves now… >.<)

These aren't particularly complex, I'm sure, but hopefully it's something for you to start on. :-)
