通过使用“C ++模式”对C99的Visual C ++支持（/ TP） [英] Visual C++ support of C99 by using "C++ mode" (/TP)
问题描述
在多大程度上
Microsoft Visual C ++
也称为：VC ++
也称为：Microsoft（R）32位C / C ++优化编译器
支持C99？
VC ++编译为C模式（def。*不是* C99！）：
cl.exe / TC c_file.c
或C ++模式
cl.exe / TP cpp_file.cpp
在C模式（/ TC）中，VC ++肯定是*不符合C99！
但是一个有趣的问题是：
当在C ++模式（/ TP）中使用时，VC ++与C99的一致性如何？
考虑到
$ b时，这一点特别有趣$ b C99库是C ++ TR1的一部分。
http://groups.google.at/group/comp.l...879cd6fca0acc8
到什么最新的VC ++（在C ++模式/ TP中）是否支持C ++ TR1？
最新VC ++（在C ++模式/ TP中）使用Dinkumware
库的程度如何？
以下是有效的C99代码：
/ ************* c_test.c *************** /
#include< stdio.h>
#include< stdbool.h>
#include< limits.h>
int main（无效）
{
bool b = true;
if（b）
printf（" hello world \ n"）;
char c = 5;
printf（"％hhd \ n"，c）;
int size = INT_MAX / 10000;
printf（"％d \ n"，size）;
char a [size];
a [0] =''a'';
a [1] =''b'';
a [2] =''\ 0'';
printf（"％s \ n"，（char *）& a）;
返回0;
}
上面的C99代码可以在VC ++上编译，只需评论第二个
行（见下文！）
/ ************* cpp_test.cpp *************** /
#include< stdio.h>
// #include< stdbool.h>
#include< limits.h>
int main（void）
{
bool b = true;
if（b）
printf（" hello world\ n"）;
char c = 5;
printf（"％hhd\\\
"，c）;
const int size = INT_MAX / 10000;
printf（"％d \ n"，size）;
char a [size];
a [0] =''a'';
a [1] =''b'';
a [2] =''\\ \\ 0'';
printf（"％s \ n"，（char *）& a）;
返回0;
}
用VC ++编译：
cl.exe \TP cpp_test.cpp
工作完美！嗯...差不多C99 ...... ???
评论赞赏，

注意：
Microsoft VC ++编译器可以免费获得：
" Visual C ++" ;:Microsoft（R）32-bit C $ C ++优化编译器
搜索
http://www.microsoft.com/downloads
for
Microsoft Windows SDK for Windows Vista
On下载页面;检查系统要求：
例如
Windows XP Professional SP2（OK！），Windows Vista等。
（否则搜索另一个兼容的Microsoft Windows SDK）
安装后：
环境变量的批处理可以如下所示：
C：\Program Files \ Microsoft Office SDK \ Windows \\\\\\\\\\\\\\\\\\\\\\\\\ /
发布/ x86 / xp
在setenv.cmd：
''颜色07''是黑色的正常白色
编译器在这里：
C：\Programme\Microsoft SDKs\Windows\v6.0\VC\Bin\cl.exe
To what extent does
Microsoft Visual C++
also called: VC++
also called: Microsoft (R) 32-bit C/C++ Optimizing Compiler
support C99?
VC++ compiles either in C mode (which is def. *not* C99!):
cl.exe /TC c_file.c
or in C++ mode
cl.exe /TP cpp_file.cpp
In C mode (/TC), VC++ is definately *not* conform to C99!
But an interesing question is:
How conform is VC++ to C99, when used in C++ mode (/TP)??
This is particularly interesting, when considering that
the C99 library is part of C++ TR1.
http://groups.google.at/group/comp.l...879cd6fca0acc8
To what extent does the latest VC++ (in C++ mode /TP) support C++ TR1?
To what extent does the latest VC++ (in C++ mode /TP) use Dinkumware
libraries?
The following is valid C99 code:
/************* c_test.c ***************/
#include <stdio.h>
#include <stdbool.h>
#include <limits.h>
int main( void )
{
bool b = true;
if (b)
printf("hello world\n");
char c = 5;
printf("%hhd\n", c);
int size = INT_MAX / 10000;
printf("%d\n", size);
char a[size];
a[0] = ''a'';
a[1] = ''b'';
a[2] = ''\0'';
printf("%s\n", (char *)&a);
return 0;
}
The above C99 code can be compiled on VC++, by just commenting the 2nd
line (see below!)
/************* cpp_test.cpp ***************/
#include <stdio.h>
//#include <stdbool.h>
#include <limits.h>
int main( void )
{
bool b = true;
if (b)
printf("hello world\n");
char c = 5;
printf("%hhd\n", c);
const int size = INT_MAX / 10000;
printf("%d\n", size);
char a[size];
a[0] = ''a'';
a[1] = ''b'';
a[2] = ''\0'';
printf("%s\n", (char *)&a);
return 0;
}
To compile with VC++:
cl.exe \TP cpp_test.cpp
Works perfectly! Hmmm... almost C99...???
Comments appreciated,
Albert
Note:
Microsoft VC++ compiler can be obtained for free:
"Visual C++": Microsoft (R) 32-bit C/C++ Optimizing Compiler"
Search
http://www.microsoft.com/downloads
for
"Microsoft Windows SDK for Windows Vista"
On download page; check the "System Requirements":
e.g.
Windows XP Professional SP2 (OK!), Windows Vista, etc.
(Otherwise search for another compatible "Microsoft Windows SDK")
After installing:
The batch-skript for environment variables can be envoked as follows
"C:\Program Files\Microsoft SDKs\Windows\v6.0\bin\setenv.cmd" /
Release /x86 /xp
In setenv.cmd:
''color 07'' is normal white on black
Compiler is here:
C:\Programme\Microsoft SDKs\Windows\v6.0\VC\Bin\cl.exe

换句话说，通过使它成为有效的C ++和无效的C99。
你的意思是什么？
In other words, by making it valid C++ and invalid C99.
What''s your point?

因为Visual C支持C90，它实际上支持大部分C99
（因为大部分C99基本上都是C90），但是它没有声明C99
一致性。微软也没有表示对支持C99的支出感兴趣，直到他们的大部分客户需要支付C99（这似乎不会在短期内发生） ）。

Because Visual C supports C90, it has de facto support for most of C99
(because most of C99 is basically C90), but it makes no claims of C99
conformance. Neither has Microsoft expressed the slightest interest in
supporting C99 until a significant proportion of their customers
requires it (which doesn''t seem to be about to happen any time soon).

我的观点是：
Maby C ++模式下VC ++与C99之间的差异很小。
（在上面的示例中，只有当前VC +
+中不知道标题（但无论如何都支持bool））
和maby这个差异会得到甚至更小，如果VC ++采用（或者更接近b $ b符合）更新的C ++标准。
Albert
My point is:
Maby the difference between VC++ in C++ mode and C99 is marginal.
(In the example above, only the header is not known in the current VC+
+ (but bool is supported anyway))
And maby this difference will get even smaller, if VC++ adopts (or
conforms more closely to) newer C++ standards.
