- c++ 单链表 不知道哪里错了emmmm求指教
-
#include
using namespace std;//节点类
class Node {
public:
int data;
Node *next;
Node() {
next=NULL;
}
};
//链表类
class LinkList {
private:
Node *head;
public:
LinkList();
void createList1(int n);};
LinkList::LinkList() {
}
//构造链表函数
void LinkList::createList1(int n) {
Node *p,*a;
p=head;
cout<<"please print in 5 numbers:"< for(int i=0;i a=new Node; //xingjianjiedian
cin>>a->data;
a->next=p->next;
p->next=a;
}
}int main() {
LinkList l;
l.createList1(5);
return 0;
}
用下面的代码试试吧，记得分配空间。另外，head指针记得保存。
void LinkList::createList1(int n) {
Node *p, *a;
int i;
cout << "Please input " << n << "numbers: ";
p = head;
for (i = 0; i < n; i++)
{
a = new Node();
cin >> a->data;
a->next = NULL;
if (i == 0)
{
p = head = a; //save head pointer
}
else
{
p->next = a;
p = p->next;
}
}
}
