C++ 类的析构函数学习笔记1

http://blog.csdn.net/leejearl/article/details/44062801

#include <vector>

#include <iostream>
#include <string>

using namespace std;


class human
{
    protected:
        string _name;
    public:
        human() 
        {
        };
        ~human()
        {
            cout << _name << endl;
        };
        string getName() {return _name;};
        void setName(string aName) {_name = aName;};
};


class man : public human
{
};


int main()
{
    man* daddy1 = new man();
    daddy1->setName("daddy1");
    delete daddy1;

    man daddy2;
    daddy2.setName("daddy2");

    return 1;

}

输出结果：

daddy1
daddy2

以上代码说明，用new 创建的类指针 需要用delete显示释放， 而用man 创建的对象则在程序结束时自动调用析构函数。
