Question

请C++的高手帮我设计一下这个程序，绝对高分悬赏！！

就是用C++编程出一个销售管理的系统，希望高手能给我提供一些帮助，就算是一小点也没关系，绝对高分悬赏！！
具体要求如下：

1 销售员信息：每个销售员包括姓名，编号，产品1销售额，产品2销售额，总销售额共5项信息。首先输入3个销售员的信息存入文件“sailer.dat”中。
2 排序：按产品1的销售额进行排序，将排序后的信息存入文件“sailer1.dat”中，按产品2的销售额进行排序，将排序后的信息存入文件“sailer2.dat”中，按总销售额进行排序，将排序后的信息存入文件“sailer3.dat”中。
3 统计：分别统计产品1的总销售额和产品2的总销售额并进行输出。
4 销售员的增加：增加一个销售员的信息，先将其添加到文件“sailer.dat”中，然后按其总销售额进行插入排序，排序后的信息仍存入文件“sailer3.dat”中。
5 销售员的减少：输入一个销售员的姓名，从文件“sailer.dat”中将其删除。
6 输出全部销售员的信息。
7 退出系统。
