C++第六篇：对象的创建

一、栈区创建对象

#include <iostream>
#include <string.h>
#include <string>

using namespace std;

class Student{
    string name = "小明";
public:
    string  Getname(){return name;}
};

int main()
{
    Student stu1;
    cout << "name:" << stu1.Getname() << endl;;
    return 0;
}

二、静态区创建对象

#include <iostream>
#include <string.h>
#include <string>

using namespace std;

class Student{
    string name = "小明";
public:
    string  Getname(){return name;}
};

//静态区存储

static Student stu1;
int main()
{
    cout << "name:" << stu1.Getname() << endl;;
    return 0;
}

三、堆区创建对象

#include <iostream>
#include <string.h>
#include <string>

using namespace std;

class Student{
    string name = "小明";
public:
    string  Getname(){return name;}
};

int main()
{
    //堆区创建
    Student* stu1 = new Student();
    cout << "name:" << stu1->Getname() << endl;
    delete stu1;
    return 0;
}

这里的new和delete实际上是对C语言中的malloc和free的封装，简单理解。
