Question

• I want to use netbeans, can you help with the following?
• Create a structure called as a studentnode that has data and pointer to the next node
• Create a constructor to initialize the linked list
• Implement the destructor that should delete the linked list once the program finishes the execution
• Implement a function to add a new node into the list with value
• Write a method to print all the values

Answer 1

#include<iostream>

using namespace std;

struct studentnode {
        string name;
        studentnode *next;

        studentnode(string n) {
                name = n;
                next = NULL;
        }
};

class studentList {

        private:
        studentnode *head;

        public:
        // constructor
        studentList() {
                head = NULL;
        }

        // destructor
        ~studentList() {
                
                studentnode *last = head;
                while(last->next != NULL) {
                        studentnode *d = last;
                        last = last->next;
                        delete d;
                }
        }

        void addToList(string name) {
                if(head == NULL) {
                        head = new studentnode(name);
                        return;
                }
                studentnode *last = head;
                while(last->next != NULL) {
                        last = last->next;
                }
                last->next = new studentnode(name);
        }

        void printList() {
                studentnode *last = head;
                while(last != NULL) {
                        cout << last->name << " ";
                        last = last->next;
                }
                cout << endl;
        }
};

int main() {
        studentList list;

        list.addToList("Jack");
        list.addToList("Rochell");
        list.addToList("Adam");
        
        list.printList();
}
