1.设计一个Per类,类中包含私有成员:姓名、年龄、指针成员身高、体重,再设计一个Stu类,类中包含私有成员:成绩、Per类对象p1,设计这两个类的构造函数、析构函数和拷贝构造函数。
#include <iostream>
using namespace std;
class Per
{
private:
string name;
int age;
double *high;
double *weight;
public:
//无参构造函数
Per()
{
cout << "我是Per::的无参构造函数" << endl;
}
//有参构造函数
Per(string name,int age,double high,double weight):name(name),age(age),high(new double(high)),weight(new double(weight))
{
cout << "我是Per::的有参构造函数" << endl;
}
//析构函数
~Per()
{
cout << "我是Per::的析构函数" << endl;
delete high;
delete weight;
}
//拷贝构造函数
Per(const Per &other):name(other.name),age(other.age),high(new double(*(other.high))),weight(new double(*(other.weight)))
{
cout << "我是Per::的拷贝构造函数" << endl;
}
void show()
{
cout << "Per::" << name << age << *high << *weight << endl;
}
};
class Stu
{
private:
int perf;
Per p1;
public:
//无参构造函数
Stu()
{
cout << "我是Stu::的无参构造函数" << endl;
}
//有参构造函数
Stu(int perf,Per p1):perf(perf),p1(p1)
{
cout << "我是Stu::的有参构造函数" << endl;
}
//析构函数
~Stu()
{
cout << "我是Stu::的析构函数" << endl;
delete &p1;
}
//拷贝构造函数
Stu(const Stu &other):perf(other.perf),p1(other.p1)
{
cout << "我是Stu::的拷贝构造函数" << endl;
}
void show()
{
cout << perf <<endl;
}
};
int main()
{
Per p1;
Per p2("fs",23,180,160);
Per p3(p2);
p3.show();
delete &p3;
cout << "********" << endl;
Stu s1;
Stu s2(90,p2);
Stu s3(s2);
s3.show();
delete &s3;
cout << "********" << endl;
return 0;
}
