My Description to DSA class for Node Class

Node.cpp

// Abdul-Wahab   GCS-s22-003
#include <iostream>
using namespace std;
class Node {
    private:
        int data;
        Node* next;
        
    public: 
        Node(int data , Node* next=NULL){
            setData(data);
            setNext(next);
        }
         
        void setData(int data){
            this->data = data;
        }
         int getData(){
            return this->data;
        }
        void setNext( Node* next){
                this->next = next;
        }
        Node* getNext(){
            return next;
        }
        
        
};

int main() {

    Node n1(2);
    Node n2 (3);
    n1.setNext(&n2);
    
    cout<<n1.getData()<<endl;
    cout<<n2.getData()<<endl;
    
    cout<<"n1 getNext "<< n1.getNext()<<endl;
    
    cout<<"n2 address "<< &n2<<endl;
       
    

    return 0;
}

Anyone can comment over here
