- The warnings just say that you can't pass a string literal with type `char[]` to a function taking a `struct Book*` parameter. The function should be declared as:
- void init_Book_types (const char* title, const char* author, int pages);
And in the constructor, `aTitle` needs to be `aTitle->title` when you call `printf`- General advise when dealing with compiler messages is to deal with them one at a time. Fix the first on in the list, re-compile, then fix the next.
- However, this is not how you do proper OO in C. You can do it, but it is somewhat cumbersome. Since you are a beginner, I'd simply advise to stay clear of OO for now. If you are curious still, there's some example [here](https://stackoverflow.com/questions/3824329/partitioning-struct-into-private-and-public-sections).

- All string assignments have to be carried out with `strcpy` since C doesn't have a string class.
