What?

That makes no sense. Your previous post makes no sense either... this is C and not C++.

Edit: perhaps you meant

Code:

typedef struct enemy{
                        int health;
                        int damage;} enemy;

I don't know if you have learned about memory allocation or not.
So I show a simple code without malloc/calloc.

Code:

#include <stdio.h>
#define MAX_ENEMY 10

typedef struct enemy_s {
   int health;
   int damage;
} enemy;

int main (void) {

    int i;
    enemy enemies[MAX_ENEMY];

// init the enemy-array
    for (i = 0 ; i < MAX_ENEMY ; i++) {
        enemies[i].health = 100;
        enemies[i].damage = 0;
    }

    return 0;
}

In this example, all enemies are in an array.
The definition on line 2 fix the maximum.
If you only play with 5 enemies, assign -1 to enemy[5].health and above.

is perfectly fine. The struct's tag does not have to be different to the typedef (struct enemy and enemy are distinct). Maybe some people think it's more readable, but my opinion differs.

I know, but do not confusing myself, i give all structs the sufix '_s'. It is like many types have the sufix '_t'.
We can also define the struct anonymous.

Code:

typedef struct {
   int health;
   int damage;
} enemy;

Edit:
It can be that a newcomer asume that this names must differ, if he/she read only my post.
Thanks to point that out, Hodor.
