写道:​​

我想知道如何从一个文本文件读取contry名称，并从另一个文本文件读取其对应的大写字母的名称.

I want to know how to read contry name from one text file and name of its corresponding capital from another text file.

您将在第二个文件中需要一些信息，该文件将资本链接到国家/地区名称.无论您决定使用哪种名称，它都可以是名称本身，互联网国家/地区名称(英国，br，ch等)，IDD代码(44、1、31等).然后，您需要阅读第二个文件，直到与国家/地区名称匹配，然后从找到的数据中选择大写字母.但是，这听起来像是一种效率很低的方法，因此最好将所有数据保存在一个文件中.然后，您可以读取整个文件，并创建名称的字典或数组，并使用某种搜索算法为每个查询选择所需的数据.

You will need some information in the second file that links the capital to the country name. This could be the name itself, the internet country designation (uk, br, ch etc), the IDD code (44, 1, 31 etc), whatever you decide on. You would then need to read the second file until you matched the country designation and select the capital from the data found. However, this sound like a very inefficient method, so it would be better to have all the data in one file. You could then read the entire file and create a dictionary or array of the names and use some searching algorithm to select the required data for each query.
