/* So the teacher built the main and a prototype for a class that builds and modifies a phone book. Right now I'm barely defining the class functions, but ran into trouble defining one of his prototypes "void erase" and "void find". I started on the void erase, which is supposed to find a person in the vector phone_book and erase it, while the "void find" simply locates the index of the desired string (name of the person being searched). I have listed the main the teacher built, the prototypes he gave us, and my work so far on defining them. You can find the two functions im asking about in the prototypes and my work. Please note that I'm not allowed to make any changes to the teachers main or prototypes. */
