Multiple inheritance in C++ is a powerful, but tricky tool, that often leads to problems if not used carefully. This article will teach you how to use virtual inheritance to solve some of these common problems programmers run into. If you're not familiar with multiple inheritance, check out ...

Now, because of virtual inheritance in the previous level, when the compiler processesJoinit will create a singleBaseobject, and thus a single vtable for theBasesubojbect ofJoin. It effectively merges the vtables ofDer1andDer2and produces a vtable that contains pointers toDer1::fooandDer2::...

Run Code Online (Sandbox Code Playgroud) 我遇到的问题是将这些问题传递给函数.我如何正确地将其中一个的实例传递给一个函数,以便它可以使用正确的虚函数,如果任何一个类型的实例都可以传递?我有一段时间没有完成继承和虚函数,所以我在这里有点生疏.(这假设函数不是类的成员函数). c++ inheritance virtual-...

C++语言的解决方案是,提供另一种可替代按“引用组合”的继承机制--虚拟继承(virtual inheritance)。在虚拟继承下只有一个共享 的基类子对象被继承而无论该基类在派生层次中出现多少次。共享的基类子对象被称为虚拟基类。 通过用关键字virtual 修正,一个基类的声明可以将它指定为被虚拟派生。例如,下列声明使得ZooAnimal...
