Learn: What is static data member in C++ programming? How to declare, define static data members and how to access with, without members function in C++? When we declare a normal variable (data member) in a class, different copies of those data members create with the associated objects....

# in-class initialization of static data member 在C++中,静态数据成员(static data member)是在类级别上共享的变量,其值在所有类对象之间共享。关于在类内部初始化静态数据成员的问题,有以下几点需要注意: ## 1. 允许在类内部初始化的类型 C++标准规定,只有字面值常量类型的静态数据成员才允许在类内部直接初始化...

All member functions are in class scope even if they are defined outside their class declaration. In the above example, the member functionadd()returns the data membera, not the global variablea. The name of a class member is local to its class. Unless you use one of the class access ...
The extern_mem_fun member function adaptor promotes the natural paradigm where private, protected, and public methods of a class process the private data of the class. The extern_mem_fun class accomplishes this by delegating the responsibility of processing elements in an STL container to a ...
