练习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
#include <iostream>using namespace std;
class Per{
private:string name;int age;float *height;float *weight;
public:Per(){cout << "Per::无参构造函数" << endl;}Per(string name,int age,float height,float weight):name(name),age(age),height(new float (height)),weight(new float(weight)){cout << "Per::有参构造函数" << endl;}~Per(){cout << "Per::析构函数" << endl;delete height;delete weight;}
};
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,float height,float weight):score(score),p1(name,age,height,weight){cout << "Stu::有参构造函数" << endl;}~Stu(){cout << "Stu::析构函数" << endl;}};
int main()
{Stu s1;Stu s2(99,"李白",66,188,166);return 0;
}
