1. 你无法断定程序会在什么地方耗费运行时间。瓶颈经常出现在想不到的地方,所以别急于胡乱找个地方改代码,除非你已经证实那儿就是瓶颈所在。 2. 估量。在你没对代码进行估量,特别是没找到最耗时的那部分之前,别去优化速度。 3. 花哨的算法在 n 很小时通常很慢,而 n 通常很小。花哨算法的常数复杂度很大。除非...

The compiler will try to perform template substitution, and it will fail on: template <typename C> static YesType& test( decltype(&C::ToString) ) ; Obviously, there is no int::ToString method so that the first overloaded method will be excluded from the resolution set. But then, the ...
“Notes on Programming in C”一文是罗布·派克 (Rob Pike)于 1989 年写的一份关于 C 语言编程的编程实践建议,包含 9 个主题的简要说明,涵盖了代码风格、程序优化、设计模式等内容。 这里是我关于这篇文章的阅读笔记。除了原文 “Introduction” 部分,其他的部分的行文都将包含如下三个部分: ...
Tables and notes 1 through 12 are based on the "Table of Intrinsic Functions," from ANSI X3.9-1978 Programming Language FORTRAN, with the FORTRAN extensions added.(1) INT If A is type integer, then INT(A) is A.If A is type real or double precision, then:if...
