什么是对象/结构体等的C ++内存布局？ [英] What is the C++ memory layout of objects/structs etc?

问题描述

在C ++中我假设C ++标准与数据成员在类中如何排列无关，就内存布局而言？

我非常想学习如何表示对象和其他C ++实体（结构体等）物理内存（我知道列表是节点到节点和数组是连续的内存 - 但所有其他方面的语言）。

编辑： x86汇编器帮助这个和理解C ++更好？

解决方案

是的，标准没有说明对象将在存储器中表示。要了解normall C ++对象的表示方式，请阅读本书： C ++对象模型。

In C++ I presume the C++ standard has nothing to do with how data members are arranged within a class, in terms of memory layout? Would I be right in thinking this is down to the compiler in question?

I'm very interested in learning how objects and other C++ entities (structs etc) are represented in physical memory (I know things like lists are node to node and arrays are continuous memory- but all the other aspects to the language).

EDIT: Would learning x86 assembler help with this and understanding C++ better?

解决方案

Yes, the standard doesn't say how the objects are to be represented in memory. To get an idea how normall C++ objects are represented read this book: inside C++ object model.
