Readme: 按照相應規則生成隨機密碼, 可作為定期修改密碼的生成器, 避免了長期使用相同密碼造成的資訊洩露問題, 製作了一個較為初級的入門款軟體, 並貼出原始碼方便大家加入或使用自己的生成規則. 本人能力有限, 若是有技術上的不足也請大牛們指正, 謝謝!

• Project: randcodeR
• Language: C/C++
• Auther: ZhuXiong
• Version: v.0.4(beta)
• Time: 2018.10.14 13:52(Shanghai Time)
• Description:
• 1. Structral improvements.
• 2. Add save model. You can use it to save your random passwords in case of forgetting your passwords.
• 3. Eazier operation. Add more hints and go back options.

== GitHub專案將會持續更新 敬請期待 ==
