关于自己是否适合编程的很简单的测试：
在报纸或杂志上随便找一段约1000字的文章，在Word中输入一遍。输完后再参考下面答案：

A里面有10处以上文字或标点错误
B里面没有文字或标点错误并敢为此跟人打赌
C里面没有文字或标点错误并且字体和排版完全与原稿一致
D打印在半透明的纸上和原稿重叠在一起检查一模一样，且自我感觉很有成就感

A不适合编程（理由：打字准确度偏低、粗心大意）
B初级程序员（理由：打字准确度很高、认真细致、自信、理解全角半角概念）
C高级程序员（理由：在B的基础上理解字体和排版也是电脑打印的重要因素、但相比D还不够偏执、精益求精、结果可验证）
D软件项目经理（理由：能针对项目给出令人信服的细致到极点的需求说明和典型测试用例。用户几乎挑不出毛病。专业！）

如果想从A变成B的话，到我的资源http://download.csdn.net/detail/zhao4zhong1/4084259里面下载“适合程序员的键盘练习”

你把 main 写成 mian 了 ...

我太马虎了，为了快，以后要慢点写代码，谢谢

[qq_30818041]

希望大家帮忙运行调试一下 谢谢
我用的Blend for Visual Studio 2015调试器
