I have to make a game, playable with 2 or 3 players, for that I need a structure which I named Player.
I wanted to ask the user for the number of "players", and do a for loop to generate players based on the number they enter, like this:

```
int playerNumbers = 0;
while (playerNumbers != 2 || playerNumbers != 3)
{
        printf("How many players are you ? 2 or 3 ? : \n");
        scanf_s("%d", playerNumbers); 

/* Error here: Unhandled exception to 0x7A72F2F6 (ucrtbased.dll) in Wheel.exe: 
An invalid parameter was passed to a function that considers invalid parameters
to be an unrecoverable cause of error. */

}
  // La boucle se répète 2 ou 3 fois
for (int i = 0; i < playerNumbers; i++)
{
        Player* player;
        if (i == 0)
        {
                player = &j1;
        }
        else if (i == 1)
        {
                player = &j2;
        }
        player = &j3;

        char tempo[50];
        printf("Enter your name : ");
        fgets(tempo, BUFFER_SIZE, stdin);
        i = 0;
        while (tempo[i] != '\n') {
                i++;
        }
        player->name = malloc(i * sizeof(char));
        strncpy_s(player->name, i, tempo, i);
        player->bank = 0;
        player->score = 0;
        player->ExtraTurn = 0;
        player->win = 0;
}

```

Problem: Error on my scanf\_s line (see the comment), and finally I have a window that opens and basically tells me that in a file "input.h" at line 1567 
Expression : result\_pointer != nullptr

I never had to deal with these errors, and wondered if there was a need for a double pointer?
