参数依赖查找 [英] argument dependent lookup
问题描述
简单程序：
#include< iostream>
int main（）{
std :: cout< ;< " bleee" << endl;
}
VC ++ .NET 2003和GCC（我认为3.3）告诉我endl是未定义的
identivier。这是正确的，还是应该通过ADL可见？
谢谢，
马丁
simple program:
#include <iostream>
int main() {
std::cout << "bleee" << endl;
}
both VC++.NET 2003 and GCC (3.3 i think) tell me that endl is an undefined
identivier. is that correct, or should endl be visible through ADL?
thanks,
martin

有趣，我不知道。
基准：也无法使用Comeau在线编译，也使用< ostream>包含。
-
答：因为它弄乱了人们通常阅读文字的顺序。
问：为什么这是一件坏事吗？
A：热门发布。
问：usenet和电子邮件中最烦人的是什么？
Interesting, and I don''t know.
Datum: fails to compile also with Comeau online, also with <ostream> included.
--
A: Because it messes up the order in which people normally read text.
Q: Why is it such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?

我很确定是正确的。在endl的
情况下重载的操作符调用是一个成员函数，所以ADL不应该适用。
I''m pretty sure that is correct. The overloaded operator call in the
case of endl is a member function, so ADL shouldn''t apply.

写的时候std ::在cout前面，你可能会错过
前面的endl？
; o）
您当然可以使用命名空间std来执行整个命名空间而不是
.
在顶部。< br $>
祝你好运，

When you write std:: in front of cout, what could you possibly be missing in
front of endl?
;o)
You could of course bring in the whole namespace instead by doing a
using namespace std;
at the top.
