請教常數建構子
請問將建構子宣告為常數，這在程式上有何不同的地方呢？
#include <iostream>
using namespace std;
class people
{
private:
int *height;
public:
void display();
people(const int *);
~people(){};
};
people:: people(const int *ht)
{ int *pt_temp=new int(*ht);
height=pt_temp;
}
void people::display()
{cout<<"高"<<*height<<"address" <<height<<endl;
}
int main()
{
int *hptr=new int(120);
people *Hobbit=new people(hptr);
cout << "Hobbit is";
Hobbit->display();
people *abcde=new people(hptr);
cout << "abcde is";
abcde-> display();
delete hptr;
system("PAUSE");
return 0;}
