c++ new 的简单使用

#include <iostream>

using namespace std;


class student
{
private:
        int age;
public:
        student(int a);
        ~student();
};
//构造函数
student::student(int a)
{
        age = a;
        cout << "student" << endl;
}
//析构函数
student::~student()
{
        cout << "~student" << endl;
}

int main()
{
        student *a = new student(2);
        //delete a;
        return 0;
}

student

student
~student
