用于支持关键字的类。 [英] Class to support keywords.

问题描述

我想编写一个类，支持对属于

C ++编程语言的关键字的操作。以下程序反复提示

用户输入关键字，直到最终输入''explicit'：


#include< iostream>

#include" KeyWord.h"


int main（）

{

KeyWord word;

while（std :: cin>> word&& word！=" explicit"）;

返回0;

}


在上面的

程序中支持KeyWord功能的类会是什么样的？这样的实现的细节是什么？ >
级？如果要使用另一套

关键字，将需要对实施进行多少更改？


我将非常感谢代码形式的帮助以及讨论。谢谢。

I want to write a class that supports operations on keywords belonging to
the C++ programming language. The following program repeatedly prompts the
user for a keyword until ''explicit'' is finally entered:

#include <iostream>
#include "KeyWord.h"

int main()
{
KeyWord word;
while (std::cin >> word && word != "explicit");
return 0;
}

What would a class that supports the functionality of KeyWord in the above
program look like?What are the details of the implementation of such a
class? How many changes to the implementation would be required if another
set of keywords was to be used instead?

I would appreciate help in the form of code as well as discussion. Thanks.

// KeyWord.h


#include< iostream>

＃ include< string>


typedef std :: string KeyWord;

// KeyWord.h

#include <iostream>
#include <string>

typedef std::string KeyWord;

// KeyWord.h

#include< iostream>
#include< string>

typedef std :: string KeyWord;

// KeyWord.h

#include <iostream>
#include <string>

typedef std::string KeyWord;

嗯，你不需要< iostream>那里。

也许只是我。

但是根据你的描述，我不清楚你想要达到的目标。 />
