Programming some game

Okay.. i'm a noob at C and i'm trying to do some game.
It's a game for 2 players. The first player inputs 4 numbers. The 2nd player tries to guess which numbers those are by inputting numbers too. If there is a correct number in wrong order, 0 will print. If there is a correct number in correct order, 1 will print. Game will end if the 2nd player gets 1111 or uses up all 10 turns.

I can't understand the array stuff much.. help me.

int i;
for(i=0;i<4;i++)
{
  if player1[i]==player2[i]
    puts("1");
  else
    puts("0");
}

Here, i increases; i specifies which parts of the arrays to compare (hence the player1[i])
