作为一个软件专业的学生，本来专业课是 Java，可惜我更喜欢 C++，所以呢，平时蹭一下 C++的课（不蹭不行啊，Java 老师说，如果我不上 Java 就必须上 C++）。
上周三，上了第一节 C++课，老师是我们院的席院长，讲得很好，虽然第一节净跟我们讲故事啦……课间，院长说，今年的大作业是一个简易的通讯录软件，按小组完成，需要实现朋友信息的添加、查询、修改等功能，一个简易不能再简易的需求了，接着，院长又给了评分细则，基础功能是80分，软件设计方案10分，图形化界面又是10分，满分一百分，谁都会算。
仔细想来，想要拿高分，基础功能肯定不能就是院长提出的那几个随便写写就行，应该需要尽量考虑更多实际情况中会需要的功能，于是我就多写了一些功能。至于软件设计方案嘛，我就先不写了，毕竟我是蹭课的，不用交作业，我只是凑到别人小组玩玩而已，所以详细设计方案我给他们大致说一下，剩下的交给他们完善就好啦。剩下的也就是图形化界面了，这个我也想好了，现在没空，QT虽然学了，但是没有实战过，所以真正使用起来，具有强迫症的我肯定问题很多，会耗费我竞赛前大量时间，等我慢慢抽空一点点完成吧，反正这不是目前最着急的事。
从上周四开始，我着手构建控制台版本的人脉关系管理软件（也就是院长说的那个通讯录），凌晨花了俩小时写了三分之一代码，第一次写这种小软件，也是遇见不少的问题，毕竟之前学过，却没有深究测试过，实际使用起来问题也是在所难免的，然后周五凌晨（其实已经是周六了）又写了一半，周末停电两天，今天中午才来电，花了一个半小时将后续完善了一下，并且测试了许久，终于完成了NIM 1.0版本，这个东西暂时不弄了，等我 QT 学得稍微好一些时再想办法弄上图形化界面，争取拿个高分回来……尽管我并没有这门课，但是帮助小组成员拿一个高分也是很棒的事情哦~~~
废话差不多已经说完了，这个代码加起来七百多行，对于一个软件而言，代码量实在是少得不要不要的，但是谁叫功能简单呢？(^__^) 嘻嘻……，下边是代码。
