array的出现代表着C++的代码更进一步“现代化”,就像std::string的出现代替了c风格字符串并且能和STL配合工作一样,array的出现则将取代语言内置的数组以及c风格的数组字符串,它提供了data()接口,使得能够获得内部数组的首地址,它提供了size(), 能够得其固定的长度,使得C++的数组也可以像Java等语言那样知道自己的leng...
static在C语言中的作用，简要地说就是为了让同名的变量或函数在各个文件之间彼此隔绝，打消他们之间的互相...

fbstring_core 负责字符串的存储及字符串相关的操作,例如 init、copy、reserve、shrink 等等。 字符串存储数据结构 最重要的 3 个数据结构 union{Char small, MediumLarge ml}、MediumLarge、RefCounted,定义在 fbstring_core 中,基本上所有的字符串操作都离不开这三个数据结构。

An object of type std::initializer_list is a lightweight proxy object that provides access to an array of objects of type const T. A std::initializer_list object is automatically constructed when: a braced-init-list is used to list-initialize an object, where the corresponding constructor acc...
