C++ 中堆栈或堆中的全局内存管理? [英] Global memory management in C++ in stack or heap?

问题描述

如果我在 C++ 应用程序中全局声明一个数据结构，它会消耗堆栈内存还是堆内存?

例如

struct AAA{.../.../.../../..}arr[59652323];

解决方案

由于我对答案不满意，并希望同一个 karjatkar 想要了解的不仅仅是一个简单的是/否答案，给你.

通常一个进程有5个不同的内存区域分配

1. 代码 - 文本段
2. 初始化数据——数据段
3. 未初始化的数据 – bss 段
4. 堆
5. 堆栈

如果您真的想了解保存在何处的内容，请阅读这些内容并添加书签:

If I declare a data structure globally in a C++ application , does it consume stack memory or heap memory ?

For eg

struct AAA
{

.../.../.
../../..
}arr[59652323];

解决方案

Since I wasn't satisfied with the answers, and hope that the sameer karjatkar wants to learn more than just a simple yes/no answer, here you go.

Typically a process has 5 different areas of memory allocated

1. Code - text segment
2. Initialized data – data segment
3. Uninitialized data – bss segment
4. Heap
5. Stack
