C++ 调用堆栈不符合标准? [英] C++ call stack not in standard?

问题描述

C++ 标准是否谈到调用堆栈?在 C++ 中如何使用堆栈和堆是常识，但我正在阅读标准并没有提到它.

Does the C++ standard talk about the call stack? It's common knowledge how stack and heap are used in C++, but I was reading through the standard and found no mention of it.

这是留给编译器实现的东西，但每个人都同意，还是在浏览文档时我错过了什么?

Is this something that's left up to the compiler implementation, but everyone agrees on, or did I miss something while browsing the doc?

推荐答案

标准中没有提及.堆栈和堆都不是.该标准描述了 C++ 程序的语法和语义(行为).实现选择按照自己的意愿实现它.

It isn't mentioned in the standard. Neither the stack nor the heap are. The standard describes the syntax and the semantics(the behavior) of C++ programs. The implementations choose to implement it as they wish.

然而，当您看到对函数的调用必须如何表现时，并没有真正广泛的选择.必须有某种堆栈来存储局部变量！

However when you see how calls to functions must behave, there isn't a really wide choice. There has to be some sort of a stack to store local variables!
