Question

求解一道C++程序设计的题目。。（职工信息管理系统）

小弟求诸位高人帮忙解决C++程序设计的问题：
要求一个职工信息管理系统。
系统功能如下：
1，创建存储该单位职工信息的存储系统，在第一次输入基本信息时，创建文件将职工信息写入文件。
2，增加职工信息，增加新职工时输入新职工的基本信息并加入文件。
3，删除某职工的基本信息，同时修改文件中相应的内容。
4，修改某职工的某些信息，如加工资，获新学位，晋升职称。
5，可以输出符合某种特征的职工信息列表，包括：
a）全体职工信息；
b）某职称的职工全部信息；
c）出生日期在某一范围的全部职工信息；
d）某一部门全部职工信息。
对了。。。该系统在内存中存储了某个单位所有职工的基本信息，对每一个职工存储:职工编号，姓名，性别，出生年月，部门，职称，最后学历，工资和婚否等信息。

如果没法提供源代码的。讲一下思路和算法也谢谢啦
