推荐答案

这并不难.首先，您需要阅读有关文件IO的信息.这是一篇很好的介绍性文章 http://www.cplusplus.com/doc/tutorial/files/ [ ^ ]

一旦学习了如何做，就需要提出数据存储格式.可能这可能会有所帮助.我会在每一行中写下x坐标，y坐标和文本

That is not hard to do. First you need to read about file IO. Here is a good introductory article http://www.cplusplus.com/doc/tutorial/files/[^]

Once you are learn how to do, you need to come up with your data storage format. May be this may help. I would write in each line, the x-coordinate, the y-coordinate and the text

10,10,Hello World<br />
10,20,Here I come<br />
10,30,What a Beauty....
