rt，代码不输出，干等在那

#include<iostream>
using namespace std;
struct node{
	int val;
	node* next;
	node(int x){
		val=x;
		next=NULL;
	}
};
int main(){
	int n;
	cin>>n;
	node* head=new node(n);
	node* p=head;
	while(cin>>n){
		node* q=new node(n);
		p->next=q;
		p=p->next;
	}
	node* m=head;
	while(m!=nullptr){
		cout<<m->val<<" ";
		m=m->next;
	}
	return 0;
}

刚回头开始啃指针qwq
