问题描述
- 在类中使用单链表,对象该怎么放到节点中?
-
我用的是基本的单链表思想,Student是我的类,我把“Student next;”直接写在Student类里面,但是我不知道怎么把对象放到节点上。这是我写的类的单链表:
/*Student *L, *s, *r;
L = (Student *) malloc (sizeof(Student));
r = L;
s = (Student *) malloc (sizeof(Student));
s->/这里不知道该写什么?*/ = stu[0];
r->next = s;
r = s;
r->next = NULL;*/
我不明白用什么来存储对象?完整的代码:
#include
#include
#include
using namespace std;//学生类的定义
class Student{public: //外部接口,公有成员函数
Student(int stuNumber,string stuName,string stuGender,string stuSchool = "USST"); //构造函数
void showStudent();Student *next;
private: //私有数据成员
int number; //学号
string name; //姓名
string gender; //性别
string school; //学校
};//学生类成员函数的具体实现 Student::Student(int stuNumber,string stuName,string stuGender,string stuSchool){ number = stuNumber; name = stuName; gender = stuGender; school = stuSchool;
}
inline void Student::showStudent(){
cout<<"t"<<number<<"t"<<name<<"t"<<gender<<"t"<<school<<endl;
}//主函数
int main(){
cout<<"t学号tt姓名t性别t学校"<<endl;//对象数组 Student stu[3] = {Student(1219010635,"孟航","男"),Student(1219010623,"余志权","男"),Student(1219010627,"闵闯","男")}; for (int i = 0;i < 3;i ++){ stu[i].showStudent(); } /*Student *L, *s, *r; //类的单链表如何实现? L = (Student *) malloc (sizeof(Student)); r = L; s = (Student *) malloc (sizeof(Student)); s->/*这里不知道该写什么?*/ = stu[0]; r->next = s; r = s;*/ return 0;
}
解决方案
你是想 把这个三个学生穿起来吧, 直接 l->next = stu[0];
stu[0].next = stu[1];
stu[1].next = stu[2];
stu[2].next = null;
