基本要求：
假设每位学生必须完成基础课50学分，专业课50学分，选修课24学分，人文类课程8学分，实践性课程20学分才能够毕业。在管理学分时，要考虑每个学分的课程类别。
功能要求：
1、系统以菜单方式工作；
2、能够通过键盘输入、修改和删除某位学生的学分；
3、查询：给定学号，显示某位学生的学分完成情况；给定某个班级编号，显示该班所有学生的学分完成情况；给定某位学生的学号，修改该学生的学分信息；
4、按照某类课程的学分高低排序；
5、能够将所有学生的学分信息读写文件。
c++的课设
不用很复杂的那种，但是必须要用链表，谢谢了
1、Student类
#include <string>
#include "Course.h"
using namespace std;
class Student{
private:
string name;
string sid;
string cid;
Course course;
public:
Student(){
name="null";
sid="null";
cid="null";
}
void setRecord(int basicCla,int professionCla,int selectCla,int cultureCla//重新设置课程学分
,int practiceCla){
course.setBasicCla(basicCla);
course.setProfessionCla(professionCla);
course.setSelectCla(selectCla);
course.setCultureCla(cultureCla);
course.setPracticeCla(practiceCla);
}
Course* getCourse(){//返回课程信息对象
return &course;
}
void setName(string name){
this->name=name;
}
void setSid(string sid){
this->sid=sid;
}
void setCid(string cid){
this->cid=cid;
}
string getName(){
return name;
}
string getSid(){
return sid;
}
string getCid(){
return cid;
}
};
2、Course类
#include <string>
using namespace std;
class Course{
private:
int basicCla;//基础课程学分50
int professionCla;//专业课程学分50
int selectCla;//选修课程学分24
int cultureCla;//人文课程学分8
int practiceCla;//实践课程学分20
public:
Course(){
this->basicCla=0;
this->professionCla=0;
this->selectCla=0;
this->cultureCla=0;
this->practiceCla=0;
}
int getBasicCla(){//获取基础课程学分
return basicCla;
}
int getProfessionCla(){//获取专业课程学分
return professionCla;
}
int getSelectCla(){//获取选修课程学分
return selectCla;
}
int getCultureCla(){//获取人文课程学分
return cultureCla;
}
int getPracticeCla(){//获取实践课程学分
return practiceCla;
}
void setBasicCla(int basicCla){//设置基础课程学分
this->basicCla=basicCla;
}
void setProfessionCla(int professionCla){//设置专业课程学分
this->professionCla=professionCla;
}
void setSelectCla(int selectCla){//设置选修课程学分
this->selectCla=selectCla;
}
void setCultureCla(int cultureCla){//设置人文课程学分
this->cultureCla=cultureCla;
}
void setPracticeCla(int practiceCla){//设置实践课程学分
this->practiceCla=practiceCla;
}
};

如有帮助，望采纳。点击我回答右上角【采纳】按钮。
你是想网上找一个用，还是全新的写一个？必须要链表和继承吗？那得单独写才行，没有现成的
上面csdn专家不是给你写好了吗
