What parts of these should i put in functions?

int player1Power = 100;
int player1Health = 100;

int player2Power = 100;
int player2Health = 100;

int player3Power = 100;
int player3Health = 100;
 and so on

int player1Power = 100;
int player1Health = 100;

int player2Power = 100;
int player2Health = 100;

int player3Power = 100;
int player3Health = 100;
 and so on
