-## 1.this指针
+## 1.This pointer
 
-相信在坐的很多人，都在学Python，对于Python来说有self，类比到C++中就是this指针，那么下面一起来深入分析this指针在类中的使用！
+I believe that many people sitting here are learning python. For Python, there is self. Analogy to C + + is this pointer. Let's analyze the use of this pointer in class.
 
-首先来谈谈this指针的用处：
+Let's first talk about the use of this pointer：
 
-（1）一个对象的this指针并不是对象本身的一部分，不会影响sizeof(对象)的结果。
+（1）This pointer to an object is not part of the object itself and does not affect the result of sizeof.
 
-（2）this作用域是在类内部，当在类的非静态成员函数中访问类的非静态成员的时候，编译器会自动将对象本身的地址作为一个隐含参数传递给函数。也就是说，即使你没有写上this指针，编译器在编译的时候也是加上this的，它作为非静态成员函数的隐含形参，对各成员的访问均通过this进行。
+（2）This scope is within the class. When accessing the non static members of the class in the non static member function of the class, the compiler will automatically pass the address of the object itself to the function as an implicit parameter. That is to say, even if you don't write this pointer, the compiler will add this when compiling. As the implicit formal parameter of non static member function, the access to each member is carried out through this.
 
-其次，this指针的使用：
+Second, the use of this pointer:
 
-（1）在类的非静态成员函数中返回类对象本身的时候，直接使用 return *this。
+（1）When the class object itself is returned in a class's non static member function, directly use return *this。
 
-（2）当参数与成员变量名相同时，如this->n = n （不能写成n = n)。
+（2）When the parameter is the same as the member variable name, 如this->n = n （不能写成n = n)。
 
-另外，在网上大家会看到this会被编译器解析成`A *const `，`A const * `，究竟是哪一个呢？下面通过断点调试分析：
 
-现有如下例子：
+The following examples are available:
 
 ```c++
 #include<iostream>
@@ -70,20 +68,20 @@ int main(){
 }
 ```
 
-对于这个简单的程序，相信大家没得问题吧，就是定义了一个类，然后初始化构造函数，并获取这个人的年龄，设置后，再获取！
 
-为了验证this指针是哪一个，现在在`add_age`处添加断点，运行后如下：
+In order to verify which this pointer is, now in 'Add'_ Add a breakpoint at "age". After running, it is as follows ：
 
 ![thiscontrust](./img/thiscontrust.png)
 
 ![genthis](./img/genthis.png)
 
-会发现编译器自动为我们加上`A* const`，而不是`A const *this`！
+You'll find that the compiler adds it to us automatically `A* const`，rather than `A const *this`！
 
-紧接着，上述还有个常函数，那么我们在对`get_age`添加断点，如下：
+Closely.There is also a constant function above，so we try to add a breakpoint at`get_age` as following：
 
 ![constthis](./img/constthis.png)
 
-会发现编译器把上述的this，变为`const A* const`，这个大家也能想到，因为这个函数是const函数，那么针对const函数，它只能访问const变量与const函数，不能修改其他变量的值，所以需要一个this指向不能修改的变量，那就是`const A*`,又由于本身this是`const`指针，所以就为`const A* const`!
+You'll find that the compiler takes the this，then it changed to`const A* const`. Because this is the const function，It can only access const variables and const functions
 
-总结：this在成员函数的开始执行前构造，在成员的执行结束后清除。上述的get_age函数会被解析成`get_age(const A * const this)`,`add_age`函数会被解析成`add_age(A* const this,int a)`。在C++中类和结构是只有一个区别的：类的成员默认是private，而结构是public。this是类的指针，如果换成结构，那this就是结构的指针了。
+，You cannot modify the values of other variables. So you need a this to point to a variable that cannot be modified，that is `const A*`,and because this is`const` pointer.
+Conclusion：This is constructed before the start of member function execution. Clear after member execution. Get above_ The age function is resolved to `get_age(const A * const this)`,`add_age`function will be paresed as `add_age(A* const this,int a)`. In C + +, there is only one difference between a class and a structure: the member of a class is private by default, while the structure is public. This is the pointer of the class. If it is replaced by a structure, this is the pointer of the structure.
