嘿所有我是编程和这个网站的新手...也许我已经咬了不止这个...但是我想要了解课程所以我发现了一个关于a的UML图表带七段显示的数字时钟。我能够辨别出UML图对于私有函数和public的想法，并且能够获得构造的单独的类文件，现在将类构造为骨架，但是如何继续这样做却不知所措。这是我到目前为止的文件： 基类
#include <iostream>
#include <string>
using namespace std;
//Declare and initialize a speed increase, or decrease
const int ROWS = 10; // move this to base class
class ClockCharacter
{
private:
//Field declarations
public:
virtual string getRow(int aRow) = 0; // pure virtual function == abstract class
}; //end class
以及帮助拼凑时钟的其他课程：
#include <iostream>
#include <string>
using namespace std;

我正在分离UML图留下的评论，我想我有几个正确的...但我仍在努力与其他人。我只有其他程序员朋友推荐的书籍，因为我是新的，有些材料有点超出我的范围。任何和所有的帮助将不胜感激。我正在查看七段显示器，并且认为我可以设计数字类似于我如何设置void initialize()功能但是我可以使用*符号而不是空格？再一次，欢迎任何帮助，欢迎回来。
