(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 ...
If a class has a constructor, each object of that type is initialized with the constructor prior to use in a program. (For more information about initialization, seeInitialization Using Special Member Functions.) Constructors are called at the point an object is created. Objects are created as...
A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.
reiterate my advice to initialize one member with another inside the constructor body, not in the member initialization list. You don't know the dependencies xfoo() has regarding the state of the X object to which it is bound. By placing xfoo() within the constructor body, you can ensure...

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...
If you have a field of your class that is the same name as the argument to your constructor, then the initialization list "does the right thing." For instance, 1 2 3 4 5 6 7 class Baz { public: Baz( std::string foo ) : foo( foo ) { } private: std::string foo; };is...
