How to add new object to the array of objects in C++?

I have two classes, namely Players and Team In the Team class, I have array of Players instances, and the MAX_SİZE = 11

#define MAX 11
class Players{
// Some private and public members 
};
class Team {
private:
    Players players[MAX];
// Some other private and public members
};

I want to implement the addNewPlayer method in my Team class. Whenever I call this method, I should be able to the add the name of the player to the end of this Players instances array, which is players. Now the function I consider is like :

void Team :: addNewPlayer(Players new_player){
       // add new_player to the end of the array
       }

I know the Stacks and Queues data structures as well. However, there is a restriction on using arrays only.
Is there any efficient way of adding new object to the array of objects in other class in general?

 players array is defined within Team class. To assign it a size; you use the variable MAX, if this variable uses an appropriate value, suppose one different from its maximum capacity that depends on the hardware, you can try creating a new array replacing the one of the class with a new length and element:

void Team::addNewPlayer(Players new_player) {

    // add new_player to the end of the array
    int newSize = sizeof(players)/sizeof(players[0]);
    Players newArray[newSize+1];
    
    for (int i=0; i < newSize; i++) {
        newArray[i] = players[i];
    }

    newArray[newSize] = new_player;
    players = newArray;
}

You'll need the current count of players in your team. Then you'll want to add a new_player to the players[currentcount]
