Provide the most general constructor that encapsulates all of the functionality of the other public constructors. Have the less-general public constructors call the most general. If you want users to have access to all the parameters at once, make the most general constructor public....
In Visual Studio 2019, the basic_string range constructor no longer suppresses compiler diagnostics with static_cast. The following code compiles without warnings in Visual Studio 2017, despite the possible loss of data from wchar_t to char when initializing out:...
struct 是 public 的,class 是 private 的。 struct 作为数据结构的实现体,它默认的数据访问控制是 public 的,而 class 作为对象的实现体,它默认的成员变量访问控制是 private 的。union 联合联合(union)是一种节省空间的特殊的类,一个 union 可以有多个数据成员,但是在任意时刻只有一个数据成员可以有值。当某个...
