Re: [問題] class中cast operator

[justdemon (人生的轉捩點)]

Try it.

#include <iostream>
using namespace std;

class intwrapaer
{
  public:
    intwrapaer(int x):val(x){}
    operator int ();
    void print();
    int operator ++(int);
   private:
    int val;

};
int intwrapaer::operator ++ (int)
{
   return val++;
}

intwrapaer::operator int()
{
   return val;
}

int main()
{
   intwrapaer ivalue(3.7);

   cout << ivalue << endl;
   int d = ivalue++;
   cout << d << endl;
   cout << ivalue << endl;

   system("PAUSE");
   return 0;
}
