一段简单的代码，运行下自己体会（Cpp与Cs析构函数）

Cpp代码：

// CppTest.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"

class tree
{
int height;
public:
tree(int initialHeight);
~tree();
void grow(int years);
void printsize();
};

tree::tree(int initialHeight)
{
height=initialHeight;
}

tree::~tree()
{
puts("inside tree destructor");
printsize();
}

void tree::grow(int years)
{
height+=years;
}

void tree::printsize()
{
printf("tree height is %d\n",height);
}

void _tmain(int argc, _TCHAR* argv[])
{
puts("before opening brace");
{
tree t(12);
puts("after tree creation");
t.printsize();
t.grow(4);
puts("before closing brace");
}
puts("after closing brace");

}

C#代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace CSTest
{
public class Tree
{
int height;

public Tree(int initialHeight)
{
height = initialHeight;
}

~Tree()
{
Console.WriteLine("inside tree destructor");
printsize();
}

public void grow(int years)
{
height += years;
}

public void printsize()
{
Console.WriteLine("tree height is {0}",height);
}
}
class Program
{
static void Main(string[] args)
{
Console.WriteLine("before openint brace");//原来C#这样写代码段也可以
{
Tree t=new Tree(12);
Console.WriteLine("after tree creation");
t.printsize();
t.grow(4);
Console.WriteLine("before closing brace");
}

Console.WriteLine("after closing brace");
}
}
}

不要忘记把想法写出来哦，哈哈。
