I am Passionate developer and esthetic keen for learning new technologies. I am Familial with technologies like unity, java, python, c, c++, dart, flutter, linux, and cyber-security. I am fascinated by the technologies and now looking forward to learn them. #include <iostream> using namespace std; //CODE FOR SELF CREATING STRUCTURE struct Node{ int id; Node *prev; Node *next; int data; }; /******************************************************************************/ //CREATING CLASS OR FINGER PRINT OF OBJECT class ListCircularDouble{ public: //CREATING GOLBAL POINTER FOR OBJECT; Node *start, *previous, *node; //ID FOR CREATING ARRAY LIKE BEHAVIOR int id=0; //SOME IMPORT INITIALIZTION WHILE CALLING CONSTRUCTOR ListCircularDouble(int data){ node=new Node; start=node; previous=node; previous->prev=node; previous->next=node; node->data=data; start->id=id; cout<<"id Number "<<id<<"="<<data<<endl; } //ADD ELEMENT IN START void addAtStart(int data){ cout<<"id Number "<<id+1<<"="<<data<<endl; id=id+1; cout<<id<<endl; node=new Node; node->data=data; node->id=id; previous->next=node; node->prev= previous; start->prev=node; node->next=start; previous=node; }; //DISPLAY LIST void display(){ Node *ptr=start; do { cout<<ptr->id<<"-> "<<ptr->data<<", "; ptr=ptr->next; } while(ptr!=start); cout<<endl; }; //ADD MULTIPLE ELEMENT WHERE N IS NUMBER OF ELEMENT void createListInt(int n){ cout<< "Add "<<n<<" Elements"<<endl; int data; for ( int i = 0; i < n; i ++ ) { cin>>data; this->addAtEnd (data); } }; }; int main(){ //Create At least 1 element By creating OBj ListCircularDouble list1(2); //ADD ELEMNTS list1.addAtStatt (20); list1.addAtStart (30); list1.display(); }
