重新定义，不同类型 [英] redefinition, different types

问题描述

标准是什么意思：


for（long i = 0; i< 0; ++ i）;

for（myclass i = 0; i< 0; ++ i）;


是允许的吗？我只是在for-loop空间中定义，不是吗？

VC6给我一个*错误*，而不仅仅是一个愚蠢的警告。

-Gernot

int main（int argc，char ** argv）{printf

（"％silto％c％cf％cgl％ ssic％ccom％c"，" ma"，58，''g''，64，" ba"，46,10）;}

What does the standart say:

for (long i=0; i<0; ++i) ;
for (myclass i=0; i<0; ++i);

is it allowed? i only is defined in the for-loop space, isn''t it?
VC6 gives me an *error*, not just a stupid warning.

标准说好了。


VC ++ 6的最佳解决方案是


#define for if（0）;否则为每个源文件顶部的
。这有效地将每个for循环放在其自身范围内。

Standard says its OK.

The best solution on VC++ 6 is

#define for if (0); else for

at the top of every source file. This effectively puts each for loop inside
its own scope.

yuck！这会给出任何问题吗？我现在看不到任何东西。我将

包括在我的afx.h中用于VC6。谢谢。

yuck! will this give any problems? I can''t see any right now. I''ll
include this in my afx.h for VC6. Thank you.

标准认为#define关键字是非法的。但是我在VC ++ 6上广泛使用了这个

，它从来没有给我带来任何问题。

Standard says its illegal to #define a keyword. However I''ve used this
extensively on VC++ 6 and its never caused any problems for me.
