Memory Layout of C Program - Code, Data, BSS, Stack, and Heap Segments: program code stored in text or code segment. Uninitialized static and global variable stored in BSS segment. Initialized static and global variable stored in data segment. Size comma
Memory Layout of a C Program A typical memory representation of C program consists of following sections. 1. Text segment2. Initialized data segment 2.1 initialized read-only area 2.2 initialized read-write area3. Uninitialized data segment4. Heap5. Stack Read Memory Layout of C Programs for ...

pi是一个局部指针,指向堆中的一块内存块,该块的大小为sizeof(int),pi本身存储在内存的栈中,生命期是main函数内 新申请的内存块在堆中,生命期是malloc/free之间 用图表示如下: 图3 例子的内存布局 总结 本文介绍了C/C++中由源程序到可执行文件的步骤,和可执行程序的内存布局,数据存储类别,最后还通过一个例子...
典型C Memory Layout 一个典型的C语言程序加载到内存中分为以下几个部分: 命令行参数 栈 堆 未初始化的数据段 有初始值的数据段 代码段 对于静态链接生成的可执行文件来说,基本就是由这六个部分组成;如果是动态链接,可能还有动态链接库加载区。关于动态链接,是一个很复杂的部分,哪天抽出时间来单独写一篇,本文...
