链表建立以及结构体的嵌套实例问题求解

Question

 小白求解答

 也不知道是什么问题总是这个样子

#include <iostream>
#include <string>
using namespace std;
const int num=6;
typedef struct Date
{
	string name;
	int score;
}Date;
typedef struct Student
{
	Date *date;
	Student *next;
}Student;
Student * Created()
{
	Student *head,*node,*t;
	head=(Student *)malloc(sizeof(Student));
	head->date=(Date *)malloc(sizeof(Date));
	node=(Student *)malloc(sizeof(Student));
	node->date=(Date *)malloc(sizeof(Date));
	head->date=NULL;
	cout<<"第"<<num<<"个节点的数据"<<endl;
	cout<<"name：";
	cin>>node->date->name;
	cout<<"\nscore：";
	cin>>node->date->score;
	head->next=node;
	node->next =NULL;
	for(int i=num-1;i>0;i--)
	{
	node=(Student *)malloc(sizeof(Student));
	node->date=(Date *)malloc(sizeof(Date));
	cout<<"第"<<i<<"个节点的数据"<<endl;
	cout<<"name：";
	cin>>node->date->name;
	cout<<"\nscore：";
	cin>>node->date->score;
	node->next=head->next;
	head->next=node;
	}
	t=head->next;
	cout<<"遍历一遍"<<endl;
	while(t!=NULL)
	{
		cout<<"name: "<<t->date->name<<"score: "<<t->date->score<<endl;
		t=t->next;
	}
	return head;
}
void main()
{
	Student *s=Created();	
}

#include <iostream>
#include <string>

using namespace std;

const int num=6;

typedef struct Date
{
	int score;
	char name[10];
}Date;

typedef struct Student
{
	Date *date;
	Student *next;
}Student;

Student * Created()
{
	Student *head,*node,*t;
	
	head=(Student *)malloc(sizeof(Student));
	head->date=(Date *)malloc(sizeof(Date));
	
	node=(Student *)malloc(sizeof(Student));
	node->date=(Date *)malloc(sizeof(Date));
	
	head->date=NULL;
	cout<<"第"<<num<<"个节点的数据"<<endl;
	
	cout<<"name：";
	cin>>node->date->name;
	cout <<node->date->name<< endl;
	
	cout<<"score：";
	cin>>node->date->score;
	cout <<node->date->score<< endl;
	
	head->next=node;
	node->next =NULL;
	
	for(int i=num-1;i>0;i--)
	{
    	node=(Student *)malloc(sizeof(Student));
    	node->date=(Date *)malloc(sizeof(Date));
    	
    	cout<<"第"<<i<<"个节点的数据"<<endl;
    	
    	cout<<"name：";
    	cin>>node->date->name;
    	cout <<node->date->name<< endl;
    	
    	cout<<"score：";
    	cin>>node->date->score;
    	cout <<node->date->score<< endl;
    	
    	node->next=head->next;
    	head->next=node;
	}
	
	t=head->next;
	cout<<"遍历一遍"<<endl;
	
	while(t!=NULL)
	{
		cout<<"name: "<<t->date->name<<"\tscore: "<<t->date->score<<endl;
		t=t->next;
	}
	return head;
}

int main()
{
	Student *s=Created();	
}

输入：

1
20
2
30
3
40
4
50
5
60
6
70
 

输出：

第6个节点的数据
name：1
score：20
第5个节点的数据
name：2
score：30
第4个节点的数据
name：3
score：40
第3个节点的数据
name：4
score：50
第2个节点的数据
name：5
score：60
第1个节点的数据
name：6
score：70
遍历一遍
name: 6    score: 70
name: 5    score: 60
name: 4    score: 50
name: 3    score: 40
name: 2    score: 30
name: 1    score: 20

 

好像是cin和String的问题我改成char name[10]了，顺便改了一下输出格式
