面向对象程序设计 C++ 上机考试B（含评分标准）

PAGE1面向对象程序设计上机考试班级：学号：姓名：时间120分钟说明：所有程序都来自教材中的例题，并对个别地方进行修改，务必仔细阅读程序。评分原则：除了特别说明外，每个题目如能得到正确结果，就得满分，否则得零分。要求：集成编码环境指定为VS2013，分析设计工具为POWERDESIGNER，要求将结果截屏粘贴在题目后面，并保存到一个PDF文件，其文件名格式为【学号_姓名.pdf】，最终提交这个文件。第一部分编码调试（每题20分，共60分）1、编辑运行程序编辑、编译、连接下面的程序，最后运行。答案：结果正确2结果正确20分2、调试程序修复下面程序的Bug。#include<iostream>usingnamespacestd;classPoint{public: Point(intx,inty){ cout<<"构造Point("<<x<<","<<y<<")"<<endl; x=x; y=y; } Point(constPoint&oldPoint){ cout<<"拷贝构造Point("<<oldPoint.x<<","<<oldPoint.y<<")"<<endl; memcpy(this,&oldPoint,sizeof(Point)); } ~Point(){ cout<<"析构Point("<<x<<","<<y<<")"<<endl; }private: intx; inty;};intmain(){ Pointp1(2,3); Pointp2(p1);}答案：构造函数Point(intx,inty)对成员变量的赋值方式不正确，改成this->x=x;this->y=y;答案不一，能正确赋值即可，2答案不一，能正确赋值即可，20分结果正确20分3、编写代码根据下面的类图和时序图编写矩形类Rectangle代码和main函数代码，贴出代码截图和运行结果截图。答案：类正确10类正确10分，main()正确5分，有运行截图5分第二部分设计程序（每题20分，共40分）1、使用类图描述程序的静态结构1）阅读下面的程序，画出程序的类图，建立程序的静态模型。#include<iostream>#include<string>usingnamespacestd;classDepartment{public: Department(stringname){ this->name=name; } voidprint(){ cout<<name<<endl; }private: stringname;};classEmployee{public: Employee(stringname){ this->name=name; } Employee(stringname,Department&department){ this->name=name; this->department=&department; } voidbelongTo(Department&department){ this->department=&department; } voidprint(){ cout<<"我是："<<name<<"，我所在的部门是："; department->print(); }private: stringname; Department*department=NULL;};intmain(){ Departmentdepartment1("研发部"); Employeeemployee1("张三"); employee1.belongTo(department1); employee1.print(); Departmentdepartment2("财务部"); Employeeemployee2("李四",department2); employee2.print();}类图各2分，连接类图各2分，连接1分2）生成代码请将题中所有成员函数的实现代码复制到其静态模型，采用正向工程生成程序的源代码，并与原来的源代码进行比较。5分5分1.将函数Employee(stringname,Department&department)的复制界面截图；2分4个文件各2分2.调试PowerDesigner2分4个文件各2分3.贴出运行结果图。答案：1.2./************************************************************************Module:Department.h*Author:MrWong*Modified:2023年6月28日11:09:36*Purpose:DeclarationoftheclassDepartment***********************************************************************/#if!defined(__上机B_Department_h)#define__上机B_Department_h单独添加#include<string>单独添加classDepartment{public:Department(std::stringname);voidprint(void)const;protected:private:std::stringname;};#endif/************************************************************************Module:Employee.h*Author:MrWong*Modified:2023年6月28日11:09:36*Purpose:DeclarationoftheclassEmployee***********************************************************************/#if!defined(__上机B_Employee_h)#define__上机B_Employee_h单独添加单独添加#include<string>#include"Department.h"classEmployee{public:Employee(std::stringname);Employee(std::stringname,Department&department);~Employee();voidbelongTo(Department&department);voidprint(void);protected:private:std::stringname;Department*department;};#endif/************************************************************************Module:Department.cpp*Author:MrWong*Modified:2023年6月28日11:09:36*Purpose:ImplementationoftheclassDepartment***********************************************************************/单独添加单独添加#include"Department.h"#include<iostream>usingnamespacestd;//////////////////////////////////////////////////////////////////////////Name:Department::Department(std::stringname)//Purpose:ImplementationofDepartment::Department()//Parameters://-name//Return:////////////////////////////////////////////////////////////////////////Department::Department(std::stringname){ this->name=name;}//////////////////////////////////////////////////////////////////////////Name:Department::print()//Purpose:ImplementationofDepartment::print()//Return:void////////////////////////////////////////////////////////////////////////voidDepartment::print(void)const{ cout<<name<<endl;}/************************************************************************Module:Employee.cpp*Author:MrWong*Modified:2023年6月28日11:09:36*Purpose:ImplementationoftheclassEmployee***********************************************************************/单独添加单独添加#include"Employee.h"#include<iostream>usingnamespacestd;//////////////////////////////////////////////////////////////////////////Name:Employee::Employee(std::stringname)//Purpose:ImplementationofEmployee::Employee()//Parameters://-name//Return:////////////////////////////////////////////////////////////////////////Employee::Employee(std::stringname){ this->name=name;}//////////////////////////////////////////////////////////////////////////Name:Employee::Employee(std::stringname,Department&department)//Purpose:ImplementationofEmployee::Employee()//Parameters://-name//-department//Return:////////////////////////////////////////////////////////////////////////Employee::Employee(std::stringname,Department&department){ this->name=name;
