练习
1.使用10.4节中所讨论的方法编写一个程序来处理平面中的点。首先定义包含两个表示坐标的成员x和y的数据类型Point。
2.借助10.4节中给出的代码和讨论的技术，提示用户输入7个（x，y）值对。当用户输入数据时，将其保存在一个名为original_points的向量中。
3.打印original_points中的数据查看结果如何。
4.打开一个ofstream，将每个点输出到名为mydata.txt的文件中。在Windows平台上，我们建议使用.txt后缀，这样使用传统的文本编辑器（如写字板）可以很容易地查看文件中的数据。
5.关闭ofstream，然后打开一个ifstream，使其与mydata.txt关联。从mydata.txt中读取数据，保存在一个名为processed_points的新的向量中。
6.打印两个向量中的数据元素。
7.比较两个向量，如果发现元素数目或值不符，打印“Something's wrong！”。
