    struct node

    int data;
        struct node *link;
        };
        struct node *top=NULL,*temp;
        void main()
        {    int choice,data;
            
                    while(1)//infinite loop is used to insert/delete infinite number of nodes    
                    {                cout << "\n1.Push\n2.Pop\n3.Display\n4.Exit\n";        
                    cout << "\nEnter ur choice:";        
                    cin >> choice;        
                    switch(choice)        
    {  case 1:
                temp=(struct node *)malloc(sizeof(struct node));
                cout << "Enter a node data :";
                cin >> data;
                temp->data=data;

                top=temp;   
                                                            
    break;

                if(top!=NULL)

                else           
              {        cout << "\nStack Underflow";                }  
                          break;   
                                         
        case 3: 
                 temp=top;  
                 if(temp==NULL)      
        {        cout << "\nStack is empty\n";  }   
    
                    while(temp!=NULL)  
        {               
                    cout << "->" <<data << "->",temp->data; 
                       temp=temp->link;            }   
                 break; 
                        
        case 4:       
            
                exit(0);        }
