C语言程序Power of Logic

Power of Logic是一个推理游戏,玩家的任务是用尽可能少的时间和步骤解开密码序列。当你输入不同的数字序列时,系统会给出提示,指示你输入的数字序列中,有多少个数字正确但位置错误,又有多少个数字和位置都正确。可惜这一游戏已经不再维护和更新了,最新的iOS设备上甚至无法下载。不过考虑到它的核心逻辑并不复杂,博主用C语言写了一个低配版。

运行效果如图:

下面附上最终版本的代码。

本文更新于2017年10月21日:
得益于C与JavaScript的某些相似性,博主成功将Power of Logic移植到Web端,制作了JavaScript版本。目前该游戏已经可以通过Galaxy Mimi>应用>原创游戏>Logic访问。移植过程全面深化了博主对于JavaScript与HTML5某些机制的理解,包括从网页实时读取内容与输出内容、通过按钮触发函数实现响应以及setInterval()clearInterval()的用法等。
