Swap a pointer between two objects

Question

I have three pointers, *player1 , *player2 and *currentPlayer .

The pointer *currentPlayer will always be pointing to either *player1 or *player2 . To switch between the two, I've been doing the following:

if (currentPlayer == player1) {
        currentPlayer = player2;
}
else {
    currentPlayer = player1;
}

My question is, is there a simpler, more elegant way to swap between these two pointers?

Answer 1

No, conceptually there's no simpler way.

Syntactically the ternary operator is a little shorter:

currentPlayer = currentPlayer == player1 ? player2 : player1;

Answer 2

如果使用数组，这也可以工作：

currentPlayer = playerArray + (currentPlayer - playerArray ^ 1);
