Hallo,

Ik probeer het volgende


#include <iostream.h>

void main (void)
{
 int a = 3;
 int * const ptr = &a;

 cout << "a : " << a << endl;
 cout << "address a : " << &a << endl << endl;

 cout << "inhoud pointer : " << *ptr << endl;
 // output : 3

 cout << "adres in pointer : " << ptr << endl;
 // output : adres van a

 cout << "adres van de pointer : " << &ptr << endl;
 // output :  foutmelding
}

als foutmelding krijg ik illegal structure operation.

Kan iemand me uitleggen waarom je geen adres kan nemen van die pointer
? En hoe kan je dat dan wel doen als het eventueel mogenlijk zou zijn?
