[Clockwise/Spiral Rule] There is a technique known as the ``Clockwise/Spiral Rule''. (顺时针螺旋法则). There are three simple steps to follow: Starting with the unknown element, move in a spiral/clockwise direction; when ecountering the following elements r…

Go's Declaration Syntax go语言声明语法 7 July 2010 Introduction Newcomers to Go wonder why the declaration syntax is different from the tradition established in the C family. In this post we'll compare the two approaches and explain why Go's declarations l…

阅读复杂的C类型声明,通常采用右左法则,也就是Clockwise/Spiral Rule (顺时针/螺旋法则). 本文将首先介绍工具(cdecl)(个人比较偏好使用工具提高学习和工作效率),然后中英文对照翻译一下著名的文章The ``Clockwise/Spiral Rule''. 1. 工具(cdecl) 1.1 命令行(cdecl) 在Ubuntu上,使用如下命令安装cdecl. $ sudo apt-get install cdecl 如何使用cdecl,举几个例子: $ cdecl -i…

C++ 中一个标识符配合着各种修饰界定符,使得标识符的本意不那么直观一眼就能看出,甚至需要仔细分析,才能知道该标识符的具体你含义. 比如: void (*signal(int, void (*fp)(int)))(int); 其中 signal 是什么? 螺旋法则 对于如何进行变量的辩识,有个非官方的 "顺时针/螺旋法则(Clockwise/Spiral Rule)" 可用来帮助辩识. 该法则的内容,简单来说,为了搞清楚一个未知标识符的含义,我们可以: 从我们需要判定的标识符开始,顺时…
