minute=t.minute;
second=t.second;

}
void Time::getTime()

}
void Time::setTime(int h,int m,int s)
{

cout<<"Error!Please Check!"<<endl;

}
hour=h;

second=s;
}
void fun0(Time t)
{
}
Time fun1()
{
Time t;
return t;
}
void main()
{
Time time0;
time0.setTime(12,5,7);
Time time1(time0);
time1.getTime();
fun0(time0);
Time time2;
time2=fun1();
}
PS:代码没问题。Time time1(time0);这句代码调用了拷贝构造函数能够理解，请问下面的两次调用拷贝构造函数如何理解？希望能给点详细的理由！先谢谢大家了！
