【项目4 - 考了语文数学的学生】
下面提供了类Stu的数据成员定义，和用于测试的main函数，参考如图的运行结果，完成类的定义，并用多文件形式组织程序

#include<iostream>   using namespace std;  class Stu  {  private:      string name;    //学生姓名       float chinese;  //语文成绩       float math;     //数学成绩       //接下去写   };        int main()  {      Stu s1,s2;      s1.setStudent("Lin daiyu", 98, 96); //对象置初值       s2.setStudent("Jia baoyu", 90, 88); //对象置初值       s1.show();//打印信息       s2.show();//打印信息       s1.setName("xue baochai");//重新置p1对象的名字       s1.show();      cout<<"s1.Name: "<<s1.getName()<<endl;//打印对象的名字       cout<<"s1.average: "<<s1.average()<<endl;//打印对象的成绩       return 0;  }

stu.h

#ifndef STU_H_INCLUDED#define STU_H_INCLUDEDusing namespace std;  #include <cstring>      class Stu  {  private:      string name;          float chinese;       float math;      public:      float average();      float sum();          void show();          void setStudent(string,float,float);       void setName(string);          string getName();    }; #endif // STU_H_INCLUDED

stu.cpp

#include<iostream>   #include<cstring>   #include "stu.h"   using namespace std;    float Stu::average()  {      return (chinese+math)/2;   //平均成绩   }  float Stu::sum()  {      return chinese+math;   //总分   }  void Stu::show()    //打印信息   {      cout<<"Name:  "<<name<<endl;      cout<<"Score:  "<<chinese<<'\t'<<math<<endl;      cout<<"average:  "<<average()<<'\t'<<"Sum:   "<<sum()<<endl<<endl;  }  void Stu::setStudent(string sName, float fChinese, float fMath)  {      name=sName; //置姓名       chinese=fChinese;   //置语文成绩       math=fMath;         //置数学成绩   }    void Stu::setName(string sName)  {      name=sName; //置姓名   }    string Stu::getName()  {      return name;   //返回姓名   }

main.cpp

#include<iostream>   #include"student.h"   using namespace std;    int main()  {      Stu s1,s2;      s1.setStudent("Lin daiyu", 98, 96);      s2.setStudent("Jia baoyu", 90, 88);     s2.show();      s1.setName("xue baochai");      s1.show();      cout<<"s1.Name: "<<s1.getName()<<endl;       cout<<"s1.average: "<<s1.average()<<endl;      return 0;  }
