C++咬文嚼字-'Pointer Trick'

晚上饭后抽空看了看如何实现一个内存管理器，涉及内存操作必定少不了指针，恰研究到offsetof这个operator，也看了它的实现，顿有所悟。 ...

C++咬文嚼字-'Functions'

关于Functions，Bjarne Stroustrup在’The C++ Programming Language’一书中是这么开篇的：‘The typical way of getting something done in a C++ program is to call a function to do it.’；另外他还阐述了一个使用Functions的原则：‘A function cannot be called unless it has been previously declared.’。 ...

C++咬文嚼字-'Evil cast'

Cast也被称为"Explicit Type Conversion"，即显式类型转换，在传统C中强制转型(cast)只有一种语法形式(T)e。Bjarne Stroustrup在’The Design and Evolution of C++’(以后称作D&E)一书的14.3小节开始就说了’无论是从语法还是从语义上, Cast都是C++里最难看的特征之一’，所以他要为cast提供A New Cast Notation. ...

C++咬文嚼字-'0 or NULL'

C程序员和C++程序员在声明空指针时做法常常是不相同的。 C程序员常常如下做： int *ptr = NULL; C++程序员则是听从Bjarne Stroustrup或者其他C++大师的教诲，坚定地如下做： int *ptr = 0; ...

C++咬文嚼字－'Hijack const'

晚上无意翻看Bjarne Stroustrup的’The C++ Programming Language Special Edition’(英文版)第94页，章节5.4 Constants一节，看到这么一句原文’C++ offers the concept of a user-defined constant, a const, to express the notion that a value doesn’t change directly.‘字眼就在directly上，既然不能directly change，那我试试indirectly change。 ...
