C++小白课本练习4

ConsoleApplication1.h 头文件定义类 Student myDate

#include <vector>
using namespace std;
#pragma once
int main();

class myDate
{
public:
	myDate(); //构造函数
	myDate(int, int, int);//构造函数
	void setDate(int, int, int);//设置日期
	void setDate(myDate);//设置日期
	myDate getDate();//设置日期
	void setYear(int);//设置年
	int getMonth();//获取月
	void printDate()const;//打印日期

private:
	int year, month, day;//成员变量，表示 年 月 日 
};
class Student {
public:
	void setStudent(string, myDate);
	void setName(string);
	string getName();
	void setBirthday(myDate);
	myDate getBirthday();
	void printStudent()const;
private:
	string name;
	myDate birthday;
};

Student 类

#include <iostream>
using namespace std;
#include <string>
#include "ConsoleApplication1.h"

void Student::setStudent(string s, myDate d)
{
	name = s;
	birthday.setDate(d);
	return;
}

void Student::setName(string n)
{
	name = n;
	return;
}
string Student::getName()
{
	return name;
}
void Student::setBirthday(myDate d)
{
	birthday.setDate(d);
	return;
}
myDate Student::getBirthday()
{
	return birthday;
}
void Student::printStudent()const
{
	cout << "姓名：" << name << "\t生日：";
	birthday.printDate();
	cout << endl;
}

myDate 类

#include <iostream>
using namespace std;
#include "ConsoleApplication1.h"

//在类体外定义成员函数
myDate::myDate() {
	year = 1970, month = 1, day = 1;
}
myDate::myDate(int y, int m, int d) {
	year = y; month = m; day = d;

}
void myDate::setDate(int y, int m, int d)
{
	year = y; month = m; day = d;
	return;
}
void myDate::setDate(myDate oneD)
{
	year = oneD.year; month = oneD.month; day = oneD.day;
	return;
}

myDate myDate::getDate()
{
	return *this;
}
void myDate::setYear(int y)
{
	year = y;
	return;
}
int myDate::getMonth() {
	return month;
}
void myDate::printDate()const
{
	cout << year << "/" << month << "/" << day;
	return;
}

第二章课本测试3验证类功能的驱动程序.cpp

#include <iostream>
using namespace std;
#include <string>
#include "ConsoleApplication1.h"
int main()
{
	Student ss;
	int y, m, d;
	string name_;
	cout << "请输入学生的姓名和生气，生日以/年月日/的次序输入";
	cin >>name_ >> y >> m >> d;
	ss.setStudent(name_, myDate(y, m, d));
	ss.printStudent();
	return 0;

}

第二章课本测试4使用指针的方式驱动程序.cpp

#include <iostream>
using namespace std;
#include "ConsoleApplication1.h"
#include <string>
int main()
{
	Student ss;
	int y, m, d;
	string name_;

	Student *sp = &ss;	//指向ss的指针sp
	cout << "请输入学生的姓名和生日，生日以/年 月 日 /的次序输入";
	cin >> name_ >> y >> m >> d;
	sp->setStudent(name_, myDate(y, m, d));
	sp->printStudent();
	return 0;

}

第二章课本测试5使用引用访问对象的成员.cpp

#include <iostream>
#include <string>
using namespace std;
#include "ConsoleApplication1.h"
int main()
{
	Student ss;
	int y, m, d;
	string name_;
	Student &sy = ss;
	cout << "请输入学生的姓名和生日，生日 以 年 月 日 的次序输入";
	cin >> name_ >> y >> m >> d;
	sy.setStudent(name_, myDate(y, m, d));
	sy.printStudent();
	return 0;
}
