Linked Classes??
Alright...this may sound like a dumb question but here it goes.
I know how to create linked lists and stuff with the *NextElement pointer inside. I was wondering if it was possible to do this same thing with classes so that you could have an array of classes that could expand in size??
Yes.
Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah
You. Fetch me my copy of the Wall Street Journal. You two, fight to the death - Stewie
You mean a linked list of objects?
A quick, limited example (just a file I have on hand for answering linked list questions and such)
Code:#define EXIT_SUCCESS 0 #define EXIT_FAILURE 1 #include <stdio.h> using namespace::std; class llist { public: int adddata(unsigned char add); llist(void); ~llist(void); void printlist(); private: unsigned char data; llist *next; }; int llist::adddata(unsigned char add) { llist *current = this; //this is a pointer to this instance of the class while (current->next) //move current to the last llist in the list current = current->next; current->next = new llist; //create a new llist at the end of the list if (current->next) //memory allocation succeeded { current->next->data=add; //store add in the new llist return EXIT_SUCCESS; } else //memory allocation failed return EXIT_FAILURE; } llist::llist() { next=NULL; data = 0; } llist::~llist() { if (next) //use recursion to delete all the llists after this one delete next; } void llist::printlist() { llist *current = this; while (current) { cout<<current->data<<endl; //display current node's data current=current->next; //move to next node } }
Away.
Thanks That Helped A Lot
