创建只读数据数组？ [英] Create readonly array of data?
问题描述
我想创建一个只读数组，然后是一个
结构的只读数组。这是我访问的数据，但我希望它能够防止意外更改
。以下是我的测试代码。
#include" stdafx.h"
struct LVC
{
unsigned short int lo;
unsigned short int hi;
};
void main （）
{
//这似乎有用
static const unsigned short int LV [4] =
{0xAC00，
0xAC1C，
0xAC38，
0xAC54};
//这个没有工作。编译器投诉
static const struct LVC [4] = {
{0xAC01,0xAC1B}，
{0xAC1D，0xAC37}，
{0xAC39,0xAC53}，
{0xAC55,0xAC6F}，
};
unsigned short i ，j;
i = LVC [2] .lo;
j = LVC [2] .hi;
}
我正在使用Microsoft Visual C ++ Express Edition
（我也想摆脱#include" stdafx.h" if
有一些编译器配置允许我这样做。$
< blockquote> Susan Riceaécrit：
//这个没有工作。编译器控制
static const struct LVC [4] = {
static const struct LVC是类型。你必须给该数组一个* name *
。
例如
static const struct LVC MyTable [4] = {
等
然后你使用这个名字：
i = MyTable [2] .lo;
j = MyTable [2] .hi;

PS
它不是无效的（）但是int main（void）。
但这是一个细节。

#include" stdafx.h"
见下文。
struct LVC
大多数人都倾向于为宏保留所有上限。
{
unsigned short int lo;
unsigned short int hi;
};
void main（）
这应该是int main（无效）
{
//这似乎有效
static const unsigned short int LV [4] =
{0xAC00，
0xAC1C，
0xAC38，
0xAC54};
//这样做没事。编译器控制
static const struct LVC [4] = {
LVC是您在上面创建的struct类型的名称。你想要什么
是这样的：
static const struct LVC LVC_array [4] = {
{0xAC01,0xAC1B}，
{0xAC1D，0xAC37}，
{0xAC39,0xAC53}，
{0xAC55,0xAC6F} ，
};
unsigned short i，j;
i = LVC [2] .lo;
j = LVC [2] .hi;
然后更改这两个名字。
}
我正在使用Microsoft Visual C ++ Express Edition
（我也想摆脱#include" stdafx.h"如果
有一些编译器配置允许我
这样做。）
这与预编译的头文件有关VC ++。我不知道
专门用来纠正Express，但检查你的项目
设置以消除任何依赖。如果你无法弄明白，那么你需要一个微软新闻组。

当你用msvc ++创建项目时
新项目 - > Win32（win32控制台应用模板自动
选中） - >
（输入项目名称） - > next->选择空项目
选项 - >完成
然后添加你需要的标题和源文件。
更简单......
new project-> selectgeneral项目类型窗口中的选项
- >完成
//这样做没事。编译器投诉
static const struct LVC [4] = {
{0xAC01,0xAC1B}，
你没有将模板命名为..已经回答上面
问候
I want to create a readonly array of data, then a readonly array of a
structure. This is data I access but I want it protected against
accidental change. The following is my test code.
#include "stdafx.h"
struct LVC
{
unsigned short int lo;
unsigned short int hi;
};
void main()
{
//This seems to work
static const unsigned short int LV[4] =
{0xAC00,
0xAC1C,
0xAC38,
0xAC54 };
//THIS DOESN''T WORK. COMPILER COMPLAINS
static const struct LVC[4] = {
{ 0xAC01, 0xAC1B },
{ 0xAC1D, 0xAC37 },
{ 0xAC39, 0xAC53 },
{ 0xAC55, 0xAC6F },
};
unsigned short i,j;
i = LVC[2].lo;
j = LVC[2].hi;
}
I''m using Microsoft Visual C++ Express Edition
(I''d also like to get rid of that #include "stdafx.h" if
there''s some compiler configuration that will allow me
to do that.)
Susan Rice a écrit ://THIS DOESN''T WORK. COMPILER COMPLAINS
static const struct LVC[4] = {static const struct LVC is the type. You have to give a *name*
to that array.
for instance
static const struct LVC MyTable[4] = {
etc
Then you use THAT name:
i = MyTable[2].lo;
j = MyTable[2].hi;
jacob
P.S.
it is not void main() but int main(void).
But that is a detail.

#include "stdafx.h"See below about this.
struct LVCIt''s generally prefered by most to reserve all caps for macros.
{
unsigned short int lo;
unsigned short int hi;
};
void main()This should be int main(void)
{
//This seems to work
static const unsigned short int LV[4] =
{0xAC00,
0xAC1C,
0xAC38,
0xAC54 };
//THIS DOESN''T WORK. COMPILER COMPLAINS
static const struct LVC[4] = {LVC is the name of struct type that you created above. What you wanted
was something like:
static const struct LVC LVC_array[4] = {
{ 0xAC01, 0xAC1B },
{ 0xAC1D, 0xAC37 },
{ 0xAC39, 0xAC53 },
{ 0xAC55, 0xAC6F },
};
unsigned short i,j;
i = LVC[2].lo;
j = LVC[2].hi;Then change these two names as well.
}
I''m using Microsoft Visual C++ Express Edition
(I''d also like to get rid of that #include "stdafx.h" if
there''s some compiler configuration that will allow me
to do that.)This has to do with pre-compiled headers in VC++. I don''t know
specifically to correct that in Express, but check your project
settings to remove any dependence. If you can''t figure it out, you''ll
need a Microsoft newsgroup.

I''m using Microsoft Visual C++ Express Edition(I''d also like to get rid of that #include "stdafx.h" if
there''s some compiler configuration that will allow me
to do that.)when u create your project in msvc++
new project->Win32(win32 console app template is automatically
selected) ->
(enter a name for the project)->next->select "empty project"
option->finish
then add the header and source files that u need.
and more simply...
new project->select "general " option from the Project type window
->finish
//THIS DOESN''T WORK. COMPILER COMPLAINS
static const struct LVC[4] = {
{ 0xAC01, 0xAC1B },
u did not name the "template" ..it has been answered above
