Reg：内存分配 [英] Reg:Memory allocation
问题描述
int x;
static int y;
int * p;
int main（void）
{
int i;
int j = 9;
int * ptr;
char * str = " GOOGLE" ;;
static int a;
int k [];
int q [] = {1,2,3} ;
注册int reg;
volatile int vol;
.......
.. ...
....
返回0;
}
根据我的说法知识在上面的程序中声明的变量
存储如下：
GLOBAL VAR'：
x，y存储在INITIALISED PART中数据段。
* p存储在STACK SEGMENT中。
LOCAL VAR'：
所有变量都存储在在STACK SEGMENT。
我说错了吗？如果我错了，请更正。
干杯&此致，
Raghu。

According to my knowledge the variables declared in the above program
are stored as follows:
GLOBAL VAR''s:
x,y are stored in INITIALISED PART OF DATA SEGMENT.
*p is stored in STACK SEGMENT.
LOCAL VAR''s:
all variables are stored in STACK SEGMENT.
Am I correct? Please correct if i''m wrong.

你做了很多关于底层硬件
架构和特定开发的实现细节
系统。如果您想询问有关此类细节的问题，请找一个
相应的新闻组。标准C不保证堆栈
段或者数据段。

You are making a lot of assumptions about the underlying hardware
architecture and the implementation details of a particular development
system. If you want to ask questions about such specifics, find an
appropriate newsgroup. Standard C makes no guarantees about "stack
segments" or "data segments".

错误。 C没有DATA SEGMENT或STACK SEGMENT这样的东西。它b / b
确实有自动存储，静态存储，动态
存储等功能，而这些存储又具有C /> $ b $中所赋予它们的功能b标准。

Wrong. C has no such things as DATA SEGMENT or STACK SEGMENT. It
does have such things as automatic storage, static storage, dynamic
storage, which in turn have the features ascribed to them in the C
standard.

为什么指针p在堆栈段中分配？
就我而言，它也应该在Data
段中分配。
why the pointer p allocated in the stack segment?
as far as I am concerned, it should also be allocated in the Data
Segment.
