struct list
{
	int info;
	struct list *next;
};
typedef struct list list;
list *start=NULL,*new1;
void insert();
void remove();
void display();
void main()
{
	int choice;
	for( ; ; )
	{
		coutchoice;
		switch(choice)
		{
			case 1:insert();
			break;
			case 2:remove();
			break;
			case 3:display();
			break;
			case 4:exit(0);
			break;
		}
	}
}
void insert()
{
	list *create_node();
	list *ptr;
	new1=create_node();
	void addnode();
	addnode();
}
list *create_node()
{
	list *new1;
	new1=(list*)malloc(sizeof(list));
	coutnew1->info;
	new1->next=NULL;
	return new1;
}
void addnode()
{
	list *prev,*ptr;
	if(start==NULL)
	{
		start=new1;
		ptr=new1;
		return;
	}
	else
	if(start->info>new1->info)
	{
