I only can add code in void order_two_players(player_t* player1_p, player_t* player2_p)

#include #include #include

void order_two_players(player_t* player1_p, player_t* player2_p) {

/* This function compares two players. If *player1_p is older than the *player2_p, swap them. In all other cases, do not swap them. Inputs: player1_p - memory location of the first player player2_p - memory location of the second player Post: After the function has been called, the age of *player1_p is always less than or equal to *player2_p age. */

}
