其执行效率在_x是一个struct member、一个class member、单一继承、多重继承的情况下都完全相同。但如果_x是一个virtual base class的member,存取速度会慢一些。 第八章、“继承“与数据成员 只要继承不要多态(Inheritance without Polymorphism) 假设有如下三个类及其继承关系: class Concreate1{ public: //... ...
struct S { public: S(); private: S(const S &); }; int main() { throw S(); // error } The problem is that the copy constructor is private, so the object can't be copied as happens in the normal course of handling an exception. The same applies when the copy constructor is...
-fnew-inheriting-ctors Enable the P0136 adjustment to the semantics of C++11 constructor inheritance. This is part of C++17 but also considered to be a Defect Report against C++11 and C++14. This flag is enabled by default unless -fabi-version=10 or lower is specified. -fnew-ttp-...

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....
struct Point{int x{0};int y{0};}; Note that we can put default initializers on member variables: C.49: Prefer initialization to assignment in constructors. 注意我们可以为成员变量设置初始化器:C.49:初始化比在构造函数中复制更好。 Note(注意) ...
