如何按日期气泡排序对详细信息进行分组和排序? [英] How to Group and Sort details by date-bubble sort?

问题描述

首先感谢您阅读本文，过去四个小时我一直在努力解决这个问题.

First off thanks for reading this, I've spent the last four hours trying to work this out.

本质上，我正在构建一个应用程序，用户在其中输入:日期、姓名、电话号码和讲师姓名到一个简单的 csv .txt 数据库文件.我已经完成了所有工作.

Essentially I'm building a application in where the user inputs: date, Name, Phone number and instructor name to a simple csv .txt database file. I've got all that working.

现在我需要做的就是以某种方式将细节组合在一起，并与其他条目分开.

Now all I need to do is somehow group the details together, and separate from other entries.

我现在想通过冒泡排序按日期对这些分组的详细信息进行排序，然后将其保存到另一个文件中.当我说排序时，我希望其他细节与日期一致.

I now want to sort these grouped details by date through a bubble sort and then save it to another file. WHen I say sort, I want the other details to go along with the date.

输入到应用程序的日期必须是:(yyMMddhhmm)例如:1308290930 = 29/08/13 9:30

The date when inputted to the application has to be: (yyMMddhhmm) Eg: 1308290930 = 9:30 on 29/08/13

我可以发布我迄今为止所做的事情.

I can post what I've done thus far.

推荐答案

我的建议是在到达记录(日期、时间等)的末尾添加一个标记.我用|".然后，当您读回数据时，将记录拆分为一个数组，然后使用该数组将它们读出.

My suggestion is to add a marker at the end of reach recoord (date, time, etc.). I use "|". Then, when you read the data back, split the records into an array, and read them out using that.

那就是:130829|0930|<姓名>|<电话号码>|等

你明白吗?
