I'd like to in my game allow my Users (players playing the game) to have an unlimited amount of Characters, but as far as my knowledge you can't even have an array of Classes, let alone an undefined array (not sure if possible in C++) of Classes. Is there a way to make this possible?

#include <list> using namespace std; list<Character*> lCharacters; lCharacters.push_back(new Characters());

Where Character is the c++ class.

Edit: nvm. I'll just make the limit of player characters to 24, shouldn't have more than that anyway.

Edit 2: I'm recieving a weird error saying that, "44 D:\My Documents\Computer Programing\C++\SW PNR II.cpp no matching function for call to `std::basic_ofstream<char, std::char_traits<char> >::basic_ofstream(std::string&)' ". Here's a cut-up part of the code,

int User::NewUserInfo() { cout << "What's your name?"; cin >> UserName; cout << endl; ofstream UserFolder ( UserName );

The last line is the one thats generating the error.

ofstream UserFolder ( UserName.c_str() );

to get the "const char*" (pointer to the string)

Matthew(22:36-40)"Teacher, which is the greatest commandment in the Law?" Jesus replied: " 'Love the Lord your God with all your heart and with all your soul and with all your mind. This is the first and greatest commandment. And the second is like it: 'Love your neighbor as yourself.All the Law and the Prophets hang on these two commandments."

Alrighty, arraylist is essentially an array which 'dynamically resizes' itself when it needs more space. What this means is that when it runs out of space, it makes a new array of size = oldSize + minAdditionalLength; and then copies over the data. If you are dealing with large amounts of data, you want to avoid those copy operations.
Worst case access: O(1); (its an array)
But it can 'randomly' slow down while copying data.

Linked list: Is essentially defined as:
template< class T >
class ListNode
{
ListNode* nextNode;
T* data;
}

Think about that and you will come to two conclusions.
A: A linked list class provides an interface to manipulate listNodes.
B: This is a very efficient form of dynamic memory storage. BUT access time is O(n) which can be very bad with large amounts of data.

For your specific case, only an addict should have more than 10 characters or some other reasonable number, so I would say LinkedList is your bet. The C++ equivalent of LinkedList is std::list, as suggested above.
