[組合語言] File Ouput 練習
英文題目已經打在程式碼中，便不多說了。
中文題目描述：
在檔案中寫入費氏數列前 47 項，用 DWORD(32 bit)儲存
輸出如下圖：
輸出的時候以 binary 方式去寫，因此會亂碼，用 notepad++ 的外掛軟件去看吧。
補充：
Notepad++ 的 Hex Editor 外掛

補充：
Notepad++ 的 Hex Editor 外掛
- 下載：http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/
- 下載後解壓縮，將 HexEditor.dll 複製到 "C:\Program Files\Notepad++\plugins" 裡面。
- 重新執行 Notepad++
- 啟動顯示 >外掛模組>HEX-Editor>View in HEX
