C语言反转单向链表的代码

学习过程中中，把内容过程中常用的内容片段做个珍藏，下边内容段是关于C语言反转单向链表的内容，应该能对大伙有较大用处。

#include "stdafx.h"

enum{N = 3};
class Node
{
public:
int var;
Node(int i):pNext(NULL), var(i){}
};

{
if(pHead->pNext->pNext != NULL)
helper(pHead->pNext, reverseHead);
else
reverseHead = pHead->pNext;
pHead->pNext->pNext = pHead;
}

{
if(NULL == pHead || NULL == pHead->pNext)
return NULL;

helper(pHead, reverseHead);
pHead->pNext = NULL;
return reverseHead;

}

{
if(NULL == pHead || NULL == pHead->pNext)
{
return NULL;
}

if(NULL == N2)
{
    N1->pNext = pHead;
    pHead->pNext = NULL;
}
else
{
    while (NULL != N2)
    {
        N1->pNext = pHead;
        pHead = N1;
        N1 = N2;
        N2 = N2->pNext;
    }

}

return N1;

}

}
printf("rn");
}

void Test()

{
