设计电子表格 [英] Designing a spreadsheet

问题描述

嗨伙计们，



我正在尝试编写一个简单的（基于控制台/文本的）电子表格程序。我是一个相对的新手。





我之前编写的程序只是2D'box'只有一种数据类型（int ，浮动，char等）。现在我需要电子表格才能在单元格中存储不同的数据类型。



我对模板有一点了解，但我无法弄清楚如何链接我的2D矢量到单元格的输入值（如果有意义的话）。



我会感激任何帮助。



我尝试了什么：



我尝试过使用智能指针，但我对它们并不是很了解失败了。

Hi folks,

I'm trying to write a simple (console/text based) spreadsheet program. I'm a relative novice.


I have written programs before where the 2D 'box' was of one data type only (int, float, char etc). Now I need the spreadsheet to be able to store different data types in the cells.

I have a little knowledge of templates but I cannot figure out how to link my 2D vector to said input values of the cells (if that makes any sense).

I'd appreciate any help.

What I have tried:

I have tried using smart pointers but I don't really know much about them and failed miserably.

推荐答案

你的数组应该是一个指针数组。然后，每个指针都需要指向实现单元格引用的对象的类对象或结构。然后，每个对象都可以实现存储，操作和显示其内容所需的方法。

Your array should probaly be an array of pointers. Each pointer will then need to point to a class object or structure that implements the object referred to by the cell. Each object can then implement the methods necessary to store, manipulate and display its contents.
