#include <stdio.h>
/*
1.代码区(text segment):存放CPU执行的机器指令,该区域只读,通常代码区共享.如果代码被频繁的执行,只需要在内存中有一份代码区.
2.数据区(data segment),明确初始化的全局变量,静态变a量(全局静态变量和局部静态变量)和常量数据(字符常量)
3.BSS区(uninitialized data segment),存放全局和静态变量未初始化的变量或者初始化为0.
4.栈区(statck):由编译器自动分配,释放,存放函数的参数直,局部变量
5.堆区(heap):用于动态内存分配.堆区一般在.bss和栈区之间,一般是由程序员去申请和分配.
