为什么我的Printlist输出最后一行是数字乱码啊🥹

void Input(stu &p)
{
p=new student;
p->next=NULL;
cout<<"请输入录入人数："<<endl;
int n;
cin>>n;
stu s;
cout<<"请分行输入学生信息"<<endl;
for(int i=0; i<n; i++)
{
s=new student;
cin>>s->num>>s->name>>s->major>>s->score;
s->next=p->next;
p->next=s;
}
cout<<"录入成功！"<<endl;
}
int Printlist(stu &p)
{
if(p->next != NULL)
Printlist(p->next);
cout<num<name<major<score<<endl;
return 0;
}
