堆和免费商店有什么区别？[重复]-Whatisthedifferencebetweentheheapandthefreestore?[duplicate]

Well, the current C++ standard only uses the term "free store" - the only use of "heap" in the Standard is to describe the heap data structure in the Standard Library. So "heap" is not a very useful term to use when trying to discuss C++ problems accurately, though of course everyone does it.

那么,当前的C ++标准只使用术语“免费存储” - 标准中唯一使用“堆”的是描述标准库中的堆数据结构。所以“堆”在尝试准确地讨论C ++问题时并不是一个非常有用的术语,当然每个人都这样做。

In Herb's book "Exceptional C++", he defines:

在Herb的书“Exceptional C ++”中,他定义:

Heap: A dynamic memory area that is allocated/freed by the malloc/free functions.

堆:由malloc / free函数分配/释放的动态内存区域。

Free Store: A dynamic memory area that is allocated/freed by new/delete.

自由存储:由新/删除分配/释放的动态内存区域。

Its possible for new and delete to be implemented in terms of malloc and free, so technically, they could be the same memory area. However, as the standard doesn't specify this, its best to treat them separatly, and not to mix malloc/delete or new/free.

它可以用malloc和free实现new和delete,所以从技术上讲,它们可以是相同的内存区域。但是,由于标准没有指定这一点,最好分开处理它们,而不是混合malloc / delete或new / free。

The free-store technically isn't the heap, just as local variables technically aren't on the stack. However, it's extremely rare in my experience to find anybody who won't accept those terms.

从技术上讲,免费存储不是堆,就像技术上局部变量不在堆栈中一样。但是,根据我的经验,找到任何不接受这些条款的人是极其罕见的。
