当然,这么一大块内存空间为了能够被更好地管理,我们通常要对内存进行布局,也就是划分功能块,我们称之为内存布局(memory layout)我们这里以c语言为例。通常我们的划分是连续的,如Fig 1所示,通常我们把连续的虚拟内存空间,从低地址位到高地址位,划分为五大段(segment): ...
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...
C/C++中由(auto、 extern、 register、 static)存储类别和对象声明的上下文决定它的存储类别。 1、自动对象(automatic objects) auto和register将声明的对象指定为自动存储类别。他们的作用域是局部的,诸如一个函数内,一个代码块{***}内等。操作了作用域,对象会被销毁。
