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 ...

In MessagePack for C# these are called Union. Only interfaces and abstracts classes are allowed to be annotated with Union attributes. Unique union keys are required.// Annotate inheritance types [MessagePack.Union(0, typeof(FooClass))] [MessagePack.Union(1, typeof(BarClass))] public interface...
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 &#…
你可以使用以下命令来检查你的程序是否有内存泄漏: bash valgrind --leak-check=yes your_program [your_program_arguments] 这将运行你的程序,并在程序结束后报告任何内存泄漏。--leak-check=yes 选项告诉 Valgrind 检查内存泄漏。 2. 使用Massif 进行堆栈分析 Massif 是 Valgrind 的一个工具,用于分析你的程序使用...
