链表（超全）C++

输入链表：

int creat(LinkList &L)//输入链表 
{
	L = new LNode;
	L -> next = NULL;
	int n, i;
	cout << "请输入元素个数：" <<endl;
	cin >> n;
	for( i = 1; i <= n; i++)
	{
		LNode *p;
		p = new LNode;
		cout << " 请输入第" << i <<"的元素。" <<endl;
		cin >> p -> data;
		p -> next = L -> next;
		L -> next = p;
	}
}

输出链表 ：

int print(LinkList &L)//输出链表 
{
	LNode *p;
	p = L -> next;  
	while (p != NULL)
	{
		cout << p -> data << "-";
		p = p -> next;
	}	
	return ok;
}

删除元素 ：

int del(LinkList &L)//删除元素 
{
	int i , j = 0;
	cout << "请删除元素的插入位置："<<endl;
	cin >> i;
	LNode *p = L, *q;
	while (p -> next && j < i - 1)
	{
		p = p -> next;
		++j;
	}	
	q = p -> next;
	p -> next = p -> next -> next;
	return ok;
}

插入元素 ：

int insert(LinkList &L)//插入元素 
{
	int i , j = 0;
	LNode *e;
	e = new LNode;
	cout << "请输入所插入的元素："<<endl;
	cin >> e -> data;
	cout << "请输入元素的插入位置："<<endl;
	cin >> i;
	LNode *p  = L;
	while (p && j < i - 1)
	{
		p = p -> next;
		++j;
	}
	e -> next = p -> next;
	p -> next = e;
	return ok;
}

查找元素和地址：

int get(LinkList &L)//查找元素 
{
	int i , j = 1;
	LNode *p = L -> next;
	cout << "输入要查找的位置： " <<endl;
	cin >> i;
	while ( p  && j < i)
	{
		p = p -> next;
		j++;
	 } 
	 cout << p -> data << endl;
	 return ok;
}
int locate(LinkList &L)//查找地址 
{
	int e , i = 1;
	LNode *p = L -> next;
	cout << "输入要查找的位置： " <<endl;
	cin >> e;
	while (p && p -> data != e)
	{
		p = p -> next;
	 } 
	 cout << "元素所在的地址为" <<p -> next << endl;
	 return ok;
}

#define ok 1
