Modifying Connect 4: Adding/Removing Pieces

[magnifik]

i am trying to write a program that is similar to connect four, but it also gives you the option of removing a piece from the bottom of the board. in this case, if there are any pieces on top of it, they will each fall down 1 row. below is my code for the process of adding a piece to the top. any suggestions on how to modify it or write a function for the opposite process would be helpful. thanks.

int drop(int b, char player){ // indicates where the piece stops at
	if(b >=0 && b<= 6) // ensure that the user chooses a column in bounds
	{
		if(place[0][b] == ' '){
			int i;
			for(i = 0;place[i][b] == ' ';i++)
				if(i == 5){ // if it hits the bottom row
                                    place[i][b] = player;
			            return i;}
			i--; // if it doesn't hit the bottom row it goes to the next open row
			place[i][b] =player;
			return i;
			
		}
		else{
			return -1;
		}

	}
	else{
		return -1;
	}

}
