深拷貝：
class Time
{
public:
int * hour, *minute ,*second;
Time(int a = 0,int b = 0 ,int c = 0)
{
hour = new int (a);
minute = new int（b）;
second = new int (c);
}
Time(const Time& a)
{
hour = new int(*(a.hour));
minute = new int(*(b.minute));
second = new int(*(c.second));
}
~Time() { delete hour,minute,second;}
void print()
{
cout<<*hour<<":"<<*minute<<“："<<*second<<" “<<endl;
}
};
int main()
{
Time t1(2,22,22);
Time t2(t1);
t1.print();
t2.print();
*(t2.hour) = 4;
t1.print();
t2.print();
return 0 ;
}
