建立链表和打印链表简单代码

struct ListNode
{
int				m_nKey;
ListNode*		m_pNext;
};

ListNode	*Head = new ListNode;
ListNode *pNode=NULL;
pNode =Head;

//建立链表并赋初值；
for (int i = 0; i < length; i++)
{
cin >> pNode->m_nKey;//给每个结点赋值；

<span style="color:#ff0000;">//重新创建下一个链表结点；
pNode->m_pNext = new ListNode;
pNode=pNode->m_pNext;</span>

}
pNode->m_pNext = NULL;<span style="color:#ff0000;">//最后为指针指向NULL；千万别忘记！</span>

//打印链表；
pNode = Head;
while (pNode->m_pNext != NULL)
{
printf("%d ", pNode->m_nKey);
pNode = pNode->m_pNext;
}
