哪位高手能给下面代码加上注释啊，我刚开始学，不太懂诶

Question

#ifndef _MyTreeNode_h_
#define _MyTreeNode_h_
#include <iostream>
#include <string>
using namespace std;

class MyTreeNode {

  public:
    char data;  
    int weight;
    int isfather;
    bool isBianLi;
    char code;
    string codes;
    MyTreeNode* left;
    MyTreeNode* right;
    MyTreeNode* father;
    MyTreeNode (char data, int weight) {
        this->weight = weight;
        this->data = data;
        this->isBianLi = false;
        this->code = '0';
        this->codes = "";
        this->isfather = 0;
        this->father = NULL;
        this->left = NULL;
        this->right = NULL;
    }
    void SetChild (MyTreeNode* left, MyTreeNode* right) {
        this->left = left;
        this->right = right;
    }
    void SetFather(int isfather) {
        this->isfather = isfather;
    }
    void SetFather(MyTreeNode* father) {
        this->father = father;
    }

};

#endif

Answer 1

定义一个类MyTreeNode，
里面有基本的类型data，weigth，isBianLi等。
还有left，rigth，father。他们是指针，是二叉树的左右叉树和父叉树。
还有构造函数MyTreeNode (char data, int weight) 和一些函数；每个类本身都有一个this指针，代表对象本身。
像构造函数的data变量，与类本身的变量data是一样的，为了区分，加this。后面函数雷同。
