笔试题（程序的输出）
分析一下这段程序的`输出 (Autodesk)
class B
{
public:
B()
{
cout<<"default constructor"<<endl;
}
~B()
{
cout<<"destructed"<<endl;
}
B(int i):data(i) //B(int) works as a converter ( int -> instance of B)
{
cout<<"constructed by parameter " << data <<endl;
}
private:
int data;
};
B Play( B b)
{
return b ;
}
(1) results:
int main(int argc, char* argv[]) constructed by parameter 5
{ destructed B(5)形参析构
B t1 = Play(5); B t2 = Play(t1); destructed t1形参析构
return 0; destructed t2 注意顺序！
} destructed t1
(2) results:
int main(int argc, char* argv[]) constructed by parameter 5
{ destructed B(5)形参析构
B t1 = Play(5); B t2 = Play(10); constructed by parameter 10
return 0; destructed B(10)形参析构
} destructed t2 注意顺序！
destructed t1
