to be honest i have no clue what to call this

Question

so I was playing around with polymorphism and inheritance and decided to do this:

#include <iostream>
using namespace std;

class enemy{
public:
void attack(){
cout<<"attack";
}
};

int main() {

enemy *e[3] = {*e, *e, *e};
e[0]->attack();
cout<<"\n";
e[1]->attack();
cout<<"\n";
e[2]->attack();

return 0;
}
I wasn't really expecting it to work but I was wondering does this have a name if so what is it? and if I were to use this in a project is this a good coding practice?

edit: the thing im talking about is in the main function

Answer 1

An array of objects. Like an array of int or string, when you create a class, you can create an array of it.

Answer 2

Run that in a C++ compiler. Pretty interesting. Only works with public inheritance. Hope this expands your knowledge.

#include <iostream>
#include <string>
using namespace std;

class Enemy{
public:
void attack(){
cout << name << " atacked!" \
<< endl;
}

void printStats(){
cout << "Name: " \
<< name << endl;
cout << "Health: " \
<< health << endl;
cout << "Damage: " \
<< damage << endl;
}

~Enemy(){
cout << name << \
" has been deleted!" << endl;
}
protected:
string name;
int health;
int damage;
};

class Goblin:public Enemy{
public:
Goblin(){
name = "Goblin";
health = 5;
damage = 2;
}

private:

};

class Skeleton:public Enemy{
public:
Skeleton(){
name = "Skeleton";
health = 3;
damage = 5;
}

private:

};

int main(){
Goblin* G1 = new Goblin;
Goblin* G2 = new Goblin;
Goblin* G3 = new Goblin;
Skeleton* S1 = new Skeleton;
Skeleton* S2 = new Skeleton;
Skeleton* S3 = new Skeleton;
Enemy* enemies[6] = \
{G1,S1,G2,G3,S2,S3};

for(int i = 0; i < 6; i++){
enemies[i]->printStats();
enemies[i]->attack();
delete enemies[i];
cout << endl;
}

return 0;
}
