嗯，编译没有任何错误可以吗？ （vc71） [英] hm, is this ok to compile without any error? (vc71)

问题描述

X级

{

public：

X（）{_ tprintf（_T（" Hey！\ n"））） ;}

};


int _tmain（int argc，_TCHAR * argv []）

{

X（qwerty）;

返回0;

}


输出：嘿！

解决方案

是的，它可以用VC7.1编译好，而且它也适用于在线

Comeau编译器。


您想指出什么？

Comeau编译器。

您想指出什么？

奇怪的是，类X在其构造函数中没有参数，我可以

仍然传递一个：qwerty，这是无处定义的。

还有一个关于为什么我问它是否正常的说明。当我意外地将我的一个

函数重命名为已经存在的类名时，这个来自

编译器的行为让我感到困惑。然后它没有编译

课程。但是当我重命名这个函数并且返回它们之前的那些它们时，我忘了在一个地方执行它，并且调用了该类的

默认构造函数而不是我的旧功能。我花了几分钟才知道发生了什么事情:)

class X
{
public:
X() {_tprintf(_T("Hey!\n"));}
};

int _tmain(int argc, _TCHAR* argv[])
{
X(qwerty);
return 0;
}

output: Hey!

解决方案

Yes, it compiles OK with VC7.1, and it''s also ok with the online
Comeau compiler.

What were you trying to point out?

What were you trying to point out?

Just strange that class X takes no parameter in its constructor and I can
still pass one: "qwerty", which was defined nowhere.

One more note about why I asked if it was ok. This behavior from the
compiler confused me yesterday when I accidentally renamed one of my
functions to an already existing class name. Then it didn''t compile of
course. But when I was renaming the function and the refereces back what
they were before, I forgot to do it at one place, and that called the
default constructor of the class instead of my old function. It took me a
few minutes to realize what was happening :)
