Hi, i'm learning the OOP and C++ at home. Now I'm at the Constructor - destructor stuff, and while going thru some exercises i got an error. Now please look at the code and help me. Thanks!

#include <iostream>
#include <conio.h>
#include <cstring>
using namespace std;

class ZnakovniNiz {
public:

	char *pok;

	ZnakovniNiz(char *p): pok(new char[strlen(p)+1]) {
 *int i;
 *for(i=strlen(p)+1;i>=0;i--)
 *	*(pok+i)=*(p+i);
	};
	ZnakovniNiz(const ZnakovniNiz &zn): pok(new char[strlen(zn.pok)+1]) {
 *int i;
 *for(i=strlen(zn.pok)+1;i>=0;i--)
 *	*(pok+i)=*(zn.pok+i);
	};
	~ZnakovniNiz() { delete [] pok;	};
};

int main(void)
{
	char strl[]="Tko je taj pokemon?";

	ZnakovniNiz PrviNiz(strl);
	cout<<strl<<endl<<PrviNiz.pok<<endl;

	ZnakovniNiz DrugiNiz(PrviNiz);
	cout<<DrugiNiz.pok<<endl;

	*(DrugiNiz.pok+3)='%';
	cout<<DrugiNiz.pok<<endl;
	cout<<PrviNiz.pok<<endl;

	getch();

	return 0;
}

The exercise is about an array of characters, there are 2 copy constructors for allocating a new memory and then copying needed stuff, and a destructor for deleting that memory.
At the end of execution i get this problem:


I also know that the program worked fine before creating a destructor.
