the code  :
/*
class creature
{
char name[20];
int strenght;
char item[20][20];
};

main()
{
creature dog1;
creature dog2;
creature tiger;

// i want to print all the creatures. cuz im making aruond 200 creatures.
// is there anyway to printout or count all the creatures.
// something like : for(i=0;i<MX_CREATURE;i++){ printCreatureState(); }

}

*/

im new to c++. any idea ?

I see two solutions:
1: Let the user of the creatures (in your case main) create a list.
2: Let the creatures themself create the list.

To do the latter:
Have a list of pointers to creatures:
std::list<creature *> CreatureList;

Add constructors to the creature class:
   creature();
   ~creature();

Let the constructor add itself to the list:
creature::creature()
{
   CreatureList.push_back(this);
}

And let the destructor remove it again:
creature::~creature()
{
   std::list<creature *>::iterator it = std::find(CreatureList.begin(), CreatureList.end(), this);
   if(it != CreatureList.end())
      CreatureList.erase(it);
   else
      std::cout << "Ups, failed to find me in the list" << std::endl;
}

I made the following test program to test it:
#include <iostream>
#include <list>

class creature
{
public:
   creature();
   ~creature();

   char name[20];
   int strenght;
   char item[20][20];
};

std::list<creature *> CreatureList;

creature::creature()
{
   CreatureList.push_back(this);
}

creature::~creature()
{
   std::list<creature *>::iterator it = std::find(CreatureList.begin(), CreatureList.end(), this);
   if(it != CreatureList.end())
      CreatureList.erase(it);
   else
      std::cout << "Ups, failed to find me in the list" << std::endl;
}

std::ostream& operator << (std::ostream& os, const creature& cr)
{
   os << cr.name;
   return os;
}

int main()
{
   creature dog1;
   strcpy(dog1.name, "Dog1");
   creature dog2;
   strcpy(dog2.name, "Dog2");
   creature tiger;
   strcpy(tiger.name, "Tiger");

   std::list<creature *>::iterator it;
   for(it = CreatureList.begin(); it != CreatureList.end(); ++it)
      std::cout << *(*it) << std::endl;
}
