2024年华为OD机试真题-用连续自然数之和来表达整数-Python-OD统一考试（C卷）

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;
    int *height;
    int *weight;
public:
    Per() {cout << "Per::无参构造函数" << endl;}
    Per(string name,int age,int height,int weight):name(name),age(age),height(new int(height)),weight(new int(weight))
    {
        cout << "Per::有参构造函数" << endl;
    }
    ~Per()
    {
        cout << "Per::析构函数" <<endl;
        delete(height);
        delete(weight);
    }
    Per(const Per &other):name(other.name),age(other.age),height(other.height),weight(other.weight)
    {
        cout << "Per::拷贝构造函数" <<endl;
    }
};

class Stu
{
private:
    double score;
    Per p1;
public:
    Stu() {cout << "Stu::无参构造函数" << endl;}
    Stu(double score,string name,int age,int height,int weight):score(score),p1(name,age,height,weight)
    {
        cout << "Per::有参构造函数" << endl;
    }
    ~Stu()
    {
        cout << "Stu::析构函数" <<endl;
    }
    
    Stu(const Stu &other):score(other.score),p1(other.p1)
    {
        cout << "Stu::拷贝构造函数" <<endl;
    }
    void show()
    {
        cout << "score = " << score << endl;
    }
    
};


int main()
{
    Stu s1(98,"二蛋",18,178,200);
    Stu s2 = s1;
    s1.show();
    s2.show();
    cout << "========================================================" << endl;
    return 0;
