 struct node
{
     int data;
     struct node *next;
}*start=NULL;
void creat()

     struct node *new_node,*current;

      new_node=(struct node *)malloc(sizeof(struct node));
     
     printf("nEnter the data : ");
     scanf("%d",&new_node->data);
     new_node->next=NULL;

      if(start==NULL)
     {
          start=new_node;
          current=new_node;
      }
     else
     {
          current->next=new_node;
          current=new_node;
     }
     
      printf("Do you want to creat another : ");
      ch=getche();
      }while(ch!='n');
}
void display()
{
     struct node *new_node;
      printf("The Linked List : n");
      new_node=start;
      while(new_node!=NULL)
     {
          printf("%d--->",new_node->data);
           new_node=new_node->next;
       }
       printf("NULL");
}

 void main()
{
     create();
     display();
}
Output : -
Enter the data : 10
Do you want to creat another :  y
Enter the data : 20
Do you want to creat another : y

 Enter the data : 30
Do you want to creat another : n

 The Linked List :
10--->20--->30--->NULL
