C++作业第四天

本文主要是介绍C++作业第四天，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

#include <iostream>
 
using namespace std;
 
class Per
{
private:
    string name;
    int age;
    int *high;
    double *weight;
public:
    //构造函数
    Per()
    {
        cout << "Per的无参构造" << endl;
    }
    Per(string name,int age,int high,double weight):\
        name(name),age(age),high(new int(high)),weight(new double(weight))
    {
        cout << "Per的有参构造" << endl;
    }
    //析构函数
    ~Per()
    {
        cout << "Per的析构函数" << endl;
        delete (high);
        delete (weight);
    }
    void show()
    {
        cout << name << " " << age << " " << *high << " " << *weight << endl;
    }
};
class Stu
{
private:
    double score;
    Per p1;
public:
    //构造函数
    Stu()
    {
        cout << "Stu的无参构造" << endl;
    }
    Stu(double score,string name,int age,int high,double weight):\
        score(score),p1(name,age,high,weight)
    {
        cout << "Stu的有参构造" << endl;
    }
    //析构函数
    ~Stu()
    {
        cout << "Stu的析构函数" << endl;
    }
    void show()

        p1.show();
    }
};
int main()
{
    Per p1;
    Per p2("张三",1,190,90.5);
    Stu s1;
    Stu s2(10.2,"李四",2,185,85.3);
    p2.show();
    s2.show();
    return 0;
}
