首先来展示一下成果：
二维码图片好像违规了，直接给链接吧网址链接
如果你扫了这个二维码就会得到一个网址，该网址是我写代码的参考，该网站讲述了如何编写一个二维码，很详细，我没有实现汉字的编码，实现了三种模式的编码，这个网址给的很详细，我也就不写了，如果再写就跟抄人家的没区别了。
下面给出生成的代码，其中有一些我自己写的工具，我会做出说明，如果不想看人家网站的话，代码中也有注释。
1.Matrix这个模板类是我做的一个二维数组的套壳，里面用的是动态申请空间，析构时自动释放
2.每个静态的值都是按照顺序来的，一般我都给了对应关系和索引如何计算
3.此类计算出来的二维码，在版本特别高时，我用微信没识别出来，没特别仔细的测试，300个2能识别（用直接跳转12306公众号了，不知道为啥），3000个2二维码已经密到有点看不清了（这个用微信扫没反应）
4.图像是使用我写的另外一个类来生成位图的，没用JPEG是因为转换没写
5.宽字节编码没写实现
6.没有解析二维码的实现
7.源代码在此这个啥都有
