课程设计账户管理系统(3)

个人帐簿管理系统记录某人每月的全部收入及各项开支情况，包括食品消费，房租，子女教育费用，水电费，医疗费，储蓄等。进入系统后可以输入和修改某月的收支情况，可以对每月的开支从小到大进行排序，可以根据输入的月份查询每月的收支情。

关于本次课程设计虽然做得有些急，但是主要的功能还是实现了，虽然比较简单，但是还是遇到好多问题，有语言上的基本问题，有算法设计上的问题，在开始由于要求比较高而且想于要快，就是前面两个的原型主要功能没有实现，最后用啦一个简单的方法把功能实现了，钱面两个就是初步实现功能的，但是效率不是很好，比如用到数组保存数据，但是主要功能的到实现了，这次就把数组的固定内存分配问题改为用单链表实现动态空间分配，由于是数据结构的课程设计，这也是老师要求的吧。对于这次的还是基本满意的，但还是有许多需要优化的地方，因为考试较多，就没有经行优化，也厚有时间再来优化，排版上也有好多问题，这次课程设计有好多感悟，今天写完的代码在今天晚上睡觉后明天起来就觉得不行了，就要删掉，有时候这种感觉就是要把所有的代码都要删掉，流程模块都要重新设计，对这中事情又爱又恨，但还是觉得重新设计比较好，这样的收获也比较大，最终付出了努力，收获还是蛮大的，下面还是把代码弄出来吧，本来代码是分还多文件的，我只能把他们合并后再贴上来，这样就更没层次了。
