这个C++错在哪里啊

没有VC，请发个错误的代码

[yyleah]

能通过编译。。但是运行时会跳出错误。。就是是否发送报告那个。。。

[yyleah]

我觉得很有可能是指针用错了。。。帮忙啦 谢谢~

[joachern]

调试一下 ，截图看看看 ？

[joachern]

你做的链表，但是第一个最好处理好 他的头和尾是同一个对象，在后期操作的时候只是插入就行了
lkT *head, *p, *rear;

head = new lkT; rear = new lkT;

p = new lkT;
这三行代码感觉不太清楚，导致后期删除内存也存在问题

额。。。我还是不太清晰。。

主要错误有下:
1思路不清
2new没有delete造成memory leak

楼主是想实现一个链表吧

lkT head,*pRear;//定义头和尾
friendT p = new friendT ;
......//对p赋值

pRear = p;
head.next = pRear;

//.....p = new friendT ;p = new friendT ;//....增加链表元素

C/C++ codelkT head,*pRear;//定义头和尾friendT p=new friendT ;

pRear= p;

谢谢！我懂了。。
