Dynamic Hash Table Implementation?!?

[CodeTheLoad]

Okay so this may be a little hard to follow, A because logic can be tough to get your head around without a visual aid & B i might not explain it the best haha.. so bare with me please...

ok so I have 4 .cpp files with their corresponding .h files; (Person.cpp/h) (ListNode.cpp/h) (LinkedList.cpp/h) and (HashTable.cpp/h)

The ListNode class contains a pointer to a persons data:

class ListNode{
    private:
        Person* data;
        ListNode* next;

However there is multiple values stored in the person class... so I was wondering what would be the best method of storing the information in the (Person.cpp/h) implementation? Is there an effective way to store a collection of values which can later be individually accessed and manipulated?????


Thanks

TO CLARIFY: i want the " Person* data " to return a collection of all the fields in the Person class (name, address, number etc.) so that i can access each field and change the data when adding a new person to the system ****THERE ARE MULTIPLE DATA TYPES

You might want to sit down and familiarize yourself more with pointers. A pointer to a person means that when you dereference it, you get the person at that address. You can mutate the data pointed to it all you want. So there's nothing special you have to do, just define your person class and then you can dereference it like normal.

will i still be able to dereference the pointer to Person if the data in the Person class is private? Or should i just make it public?

Originally I had made the Persons data private with the intention of using accessors and mutators in the .cpp file. If I was to make the data public in the Person.h file would that not make the Person.cpp file irrelevant?.. as i would no longer need any functions to access the data??

ListNode files include the Person.h file btw

Okay, before we go any further, we might need to take a step back. In C++ it's easy to start drowning in details. Before we go down that road, let's discuss your algorithm from a higher level.

First and foremost, what are we trying to accomplish here? It seems to me like you're trying to create a Persons database which you can query and then use to mutate the Person's data. Is this correct?

[CodeTheLoad]

Yeah, that's pretty much the goal. I want to implement it as a chained hashtable, using the hash table as a table of buckets to store individual linked lists. Each List Node then has a pointer to a person (Person* data) and a next pointer.

I have now made the Person class fields (string name, int number, string address etc) public so that the data can be mutated by using a pointer of the type person(Person* data), it seems to be working now.. well i haven't tested it yet but it has compiled alright anyway haha
