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 ...
In this tutorial we talked of memory layout of a C program, and its various segments (text or code segment, data, .bss segments, stack and heap segments). Hope you have enjoyed reading this article. Please dowrite usif you have any suggestion/comment or come across any error on this pa...

The stack area contains the program stack, a LIFO structure, typically located in the higher parts of memory. On the standard PC x86 computer architecture, it grows toward address zero; on some other architectures, it grows in the opposite direction. A “stack pointer” register tracks the top...

1 vote Anurag Gupta 10 years ago Hello sir,Your explanation about memory layout of a C program is very good but there is one fact that in OS, programs are considered as processes and every process that is entering into running state, Four segments are created - Data segement, code segment...
现在有c语言代码如: // file name memory-layout.c #include <stdio.h> int main(void) { return 0; } 我们可以通过指令size对其使用的各部分的内存进行报告,如下所示: [narendra@CentOS]$ gcc memory-layout.c -o memory-layout [narendra@CentOS]$ size memory-layout ...
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...
1.4Memory layout of an executing program Computer memory consists of number of storage locations, or cells, each of which has a unique numericaddress. Addresses are usually written in hexadecimal. Each storage location can contain a fixed number ofbinary digits. The most common size is one byte...
