是这样的,我做了很多测试
如果你功力可以,你干脆看看<<inside the c++ object model>>

好,如果是中文的话..相信我还是可以的..

the temp object will be usually created by object assignment, or a function return an object(not reference), and something like you above spoken. But, you must know, it depens on the compiler that you used. That mean, it will be differently handelt. For example by assignment, not always an temp Object will be created.

yep,just like what you've said above
eg:
Sample s1=Sample s2(.....);
..............
sometimes the compiler will creat a temp object and make a copy to s1
but sometimes may not!

My appreciation here!

kan lai ni xiang kao kao da jia a.

这个绝对是会调用copy constroctor
因为 Sample s1=Sample s2(.....)相当于 Sample s1(s2)

My apologize,I misnunderstood you a little bit
I mean:
Sample s1=Sample (...);

Then,what about this time?

#include<iostream>

using namespace std;

class text
{
public:
text(){ cout << "hello constroctor" <<endl;}
text(const text &t){ cout << "hello copy" << endl;}
};

int main()
{
text t1 = text(text());
text t2 = text();
}

我的编译器是vc.net做了优化,所以调用 text()但是按照语法,是调用text(text &),

No intention to have a test for oyur guys here,
you two have been elcted to be the "Ban Zhu"here,
but i'm just a freshman for C plus plus...
you flattered me a lot!
Thanks...

wo bu shi ban zhu, zhi shi yi ge xiao bing.
