有谁帮忙解决一个数组的问题

我有一个文本文件，里面有大量的数据。有4000行17列，第一列是时间，其余的列都是小数点后两位的数，我想把其中的一列提取出来画曲线图。我想把所有的数据赋值给一个二维数组后来操作应该怎样赋值呢？

不想多说了，自己看源码

用stringlist是以行为单位的

COPY呗 然后 写成一行不用加{} 他会自动分行的 比如你的数据是 1 2 3
                                                                                       4 5 6
                                                                                       7 8 9
你COPY过去后就写成 float i={123456789};
然后定义指针来读取啊
具体请看我的日志 我写了代码和注释

如果觉得好就给最佳啊

话说你学了指针吗 这个方法我是用到了指针
不懂的话可以联系我 或者看甲鱼的视频 不懂可以追问

他问的是Delphi 吧，你那是C{:5_93:}

不好意思 我是在提问互助里看的 没看到是 delphi7{:5_91:}

看看这篇文章 http://www.xuedelphi.cn/wenzhang/pascal/2007/12/200712302013.htm

不懂可以问

我建议你把数据文件发上来，要先搞清楚你的数据的分隔的方式是什么，
