C从入门到放弃篇1

各位新入坑C语言的朋友，你们有福了因为你们遇到了我，我会带你放弃C语言，哈哈哈哈哈。

其实，学任何东西都是循序渐进的，在学习的初期投入更多的精力，将来你会越学越快。我相信，放弃是最容易的事情，而坚持学习的你很靓。如果不怕吃苦就跟我一起来吧。反正，人生就像打电话，不是你先挂就是我先挂，看谁先放弃，哈哈哈。Here insert one tip：Maybe my passage will join some foreign English words in future.（这里加个提示：也许我的文章将来会加入一些外国英语单词），In my opinion,it is benifit to you,could help you easliy read the professional computer passages。话不多说，上代码：
