[computer-go] C++ pointer question

[Peter Drake]

Okay, I've got this method in my BitBoard class:

void dilate() // Expand to include all adjacent points
{
	BitBoard temp;
	temp.bits[0] = bits[0] | (bits[0] << 1) | (bits[0] >> 1) | bits[1];
	temp.bits[board_width - 1] = bits[board_width - 1] | (bits 
[board_width - 1] << 1)
		| (bits[board_width - 1] >> 1) | bits[board_width - 2];
	for (unsigned row = 1; row < board_width - 1; row++) {
		temp.bits[row] = bits[row] | (bits[row] << 1) | (bits[row] >> 1) |  
bits[row - 1] | bits[row + 1];
	}
	for (unsigned row = 0; row < board_width; row++) {
		bits[row] = temp.bits[row];
	}
}

Is there some way to avoid that second for loop? I tried "this =  
temp" and "*this = *temp", but the compiler isn't happy with either.

Thanks,
