在本章中,我们将完全用C语言,实现面向对象中最重要的几个概念,分别是继承,覆盖。我们先看实现后的调用: int main (int argc, char ** argv) { void * p; while (* ++ argv) { switch (** argv) { case &#…
创建一个 RoundedRectangle 对象实例,它的实例变量在内存的分布是: 内容分析: “isa”:The NSObject instance variable is called isa because inheritance sets up an “is a” relationship between the subclass and the superclass; that is, a Rectangle is a Shape, and a Circleis a Shape. Code that ...

Private virtual base classes and indirect inheritance Previous versions of the compiler allowed a derived class to call member functions of its indirectly derived private virtual base classes. This old behavior was incorrect and doesn't conform to the C++ standard. The compiler no longer accepts ...
The iostream library is a class hierarchy implemented using both virtual and multiple inheritance. The C++ Primer concludes with an Appendix that provides a discussion and program example of each generic algorithm in alphabetical order for easy reference. Finally, whenever one writes a book, what ...
