你能解释一下这个指针的概念吗？ [英] Can you explain the concept of the this pointer?

问题描述

我需要理解这个指针概念，最好用一个例子。

所以请使用简单的语言，这样我就可以更好的理解了。

解决方案

此是指向其类的实例的指针

如果你已经声明了一个类，它有一个私有成员 foo bar 可通过 bar ， foo code> this-> foo ，但不通过 instance-> foo b

I need to understand this pointer concept, preferably with an example.

I am new to C++, so please use simple language, so that I can understand it better.

解决方案

this is a pointer to an instance of its class and available to all non-static member functions.

If you have declared a class, which has a private member foo and a method bar, foo is available to bar via this->foo but not to "outsiders" via instance->foo.
