Class例程之3析构函数

#include <iostream>
#include <string>

using namespace std;
class CStudent
{
        public:
            CStudent();
            CStudent(char *name,int age);
            ~CStudent();
            void init(char *name,int age);
            void output();
        
        private:
            char m_name[20];
            int m_age;
};

CStudent::CStudent()
{
           strcpy(m_name,"TOM");
           m_age = 0;
}

CStudent::CStudent(char *name,int age)
{
        strcpy(m_name,name);
        m_age = age;
}

CStudent::~CStudent()
{
    cout<<"The object is deconstructing!"<<endl;
}

void CStudent::init(char *name,int age)
{
        strcpy(m_name,name);
        m_age = age;
}

void CStudent::output()
{
        cout<< m_name <<"               " <<m_age<<endl;
}

int main()
{
        CStudent stu1;
        CStudent *p = &stu1;
        p->init("Peg",22);
        (*p).output();

        return 0 ;
}

明白，析构函数的特性，用法。
