[happyforever]

说简单点，就是做善后工作，不要出现什么异常

[maoxianwang]

偶上边四层的说的对

[Liusp]

是用来释放对象的

[jimw]

用来释放你在类中定义的一些对象，如内存，名柄,关闭DB或Socket连接 etc.

[linhui]

析构函数： 主要是释放对象所占的内存

你可以定义它 如你没有定义系统会自动调用隐视的析构函数来释放

其实你没有必要来着问这么简单的问题 （ 基础C++ ） 上都有 OK！！！！

[Last_Dodo]

Destructor has only one task that is to release all the resources owned by this class. The resource could be memory (including shared memory), opened files, network connections, etc. The key is that if the class is the owner of the resources the destructor has to release them otherwise it could cause problem in your process (if the OS handle resource release when a process dies) or the whole machine (if the OS does not release resource when a process dies).
