(Simple) Every constructor should initialize every member variable (either explicitly, via a delegating ctor call or via default construction). (简单)所有的构造函数都应该初始化每个成员(可以明确地通过委托构造函数或默认构造函数) (Simple)
代码运行次数:0 classFoo{int m1;int m2;public:Foo(int x):m2{x},m1{++x}{}// BAD: misleading initializer order// ...};Foox(1);// surprise: x.m1 == x.m2 == 2 Enforcement(实施建议) (Simple) A member initializer list should mention the members in the same order they are declared...

編譯器錯誤 C3442正在將等位的多個成員初始化: 'member1' 和 'member2' 編譯器錯誤 C3443'class' 的預設成員初始設定式為遞迴 編譯器錯誤 C3444空白彙總類別 'class' 必須以 '{}' 初始化 編譯器錯誤 C3445'type' 的 copy-list-initialization 不得使用明確的建構函式 ...
静态初始化:编译期进行的初始化,所谓编译期进行的初始化,即在编译期直接将数据放在程序虚拟地址空间的数据段中,因此静态初始化在程序加载到内存时完成.静态初始化又分为 zero-initialization(零初始化)和constant initialization(常量初始化),zero-inltilization指的是对于没有指明初始化式的全局对象,就由编译器用0初始...
class class_name { access_specifier_1: member1; access_specifier_2: member2; ... } object_names; class_name是一个有效的标识符即可,object_names可选,声明体包含的称为成员(members),既可以是数据也可以是函数声明,访问权限(access specifiers)可选。 相比数据结构,类增加了函数和访问权限,访问权限使用...
template < class type > foo< type >::foo( type t ) { // may or may not be a good idea depending on the actual type of type _t = t; } This has led some programmers to insist rather aggressively that all member initialization be done ...
了解typename 的双重意义(声明 template 类型参数是,前缀关键字 class 和 typename 的意义完全相同;请使用关键字 typename 标识嵌套从属类型名称,但不得在基类列(base class lists)或成员初值列(member initialization list)内以它作为 basee class 修饰符) 学习处理模板化基类内的名称(可在 derived class templates ...
