(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) Default arguments to constructors suggest an in-class initializer ...
Compiler error C2614 'class': illegal member initialization: 'identifier' is not a base or member Compiler error C2615 'offsetof' cannot be applied to non-class type 'type' Compiler error C2616 'conversion': cannot implicitly convert a non-lvalue 'type1' to a 'type2' that is not const...
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...

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...

If you develop a dialog box by hand, you add the necessary member variables to the derived dialog-box class yourself, and you add member functions to set or get these values. A modal dialog box closes automatically when the user presses the OK or Cancel buttons or when your code calls th...
