nonstatic data members 和 static data members 在C++中,类的数据成员可以分为非静态数据成员(non-static data members)和静态数据成员(static data members)。 非静态数据成员(non-static data members): 非静态数据成员是类定义中没有使用static关键字声明的数据成员。对于这些数据成员,每个类的实例都有各自独立的...

Once you define a static data member, it exists even though no objects of the static data member's class exist. In the above example, no objects of classXexist even though the static data memberX::ihas been defined. Static data members of a class in namespace scope have external linkage...
Static data members can be referred to without referring to an object of class type. The number of bytes written usingBufferedOutputobjects can be obtained as follows: long nBytes = BufferedOutput::bytecount; For the static member to exist, it is not necessary that any objects of the class ...
因为上述问题,会导致存取static data members引入一些不规则性。同样在深度探索C++对象模型针对该不规则性有如下描述 如果class的设计者把static data member声明为nonpublic(这一直被视为是一种好的习惯), 那么他就必须提供一个或者多个member functions来存取该member。因此,虽然你不可以靠class object来存取一个static...

Static data members are not associated with any object. They exist even if no objects of the class have been defined. If the static member is declared thread_local(since C++11), there is one such object per thread. Otherwise, there is only one instance of the static data member in the ...
What’s more, since C++17, we can initialise static data members thanks to inline variables: structOtherType{staticconstintvalue=10;staticinlinestd::stringclassName="Hello Class";OtherType(){}} There’s no need to defineclassNamein a corresponding cpp file. The compiler guarantees that all comp...
