[1] 即printf

[2] class wiimote : public wiimote_state , 7表示最多可能裝置數量

[3]  wiimote *next = new wiimote;   創建一個wiimote物件叫做 next

[4] next->Connect(wiimote::FIRST_AVAILABLE) 連線失敗回傳false

[5] 表示[4]連線成功, 並將之存入extra_motes陣列內

[6] (白色字)列印"   also found wiimote "

[7] (亮綠字)列印 發現裝置編號

[8] next->IsBalanceBoard() 判斷是否為 Balance Board, 若是則(白色字)列印"(Balance Board)"

[9] Beep(1000 + (detected*100), 100): 根據裝置編號決定Beep頻率
