本人是个菜鸟，请教各位大师：用C++实现：自己设置一个单词库，再用cin输入一些单词，如果发现输入的单词是单词库中的，则蜂鸣器报警

    string input;
    cout << "请输入C++ namespace 标准库关键字(输入quit退出)：" << endl;
    while (cin >> input) {
        if (findStringInVec(input, StdLibKey))
            cout << input << " 是标准库关键字\n";
        else
            cout << input << " NO!\n";

        if (input == string("quit")) {
            return -1;
        }
    }
    return 0;
}

编译器 需要开启 C++0X 标准

收益匪浅，谢谢各位大师

反正就是用个循环，每次读取库中的一个单词，之后与输入的单词对比。

[灼眼的超哥]

功能和大致的工作流程都已经被你说出来了，剩下的就是翻译成C++语言的代码了。
如果发现输入的单词是单词库中的：

while()
{
   //每循环一次读取单词库中的下一个单词，代码自己写

   if(输入的单词 == 单词库中的单词)
   {
     //执行让蜂鸣器报警的代码
     break;
   }
}

#include <iostream>
#include <list>
#include <string>
#include <algorithm>
using namespace std;


int main()
{
list<string> wordList;
string word;
list<string>::iterator iter;
cout << "input words, (q) ends input" << endl;
while(cin >> word)
{
if (word == "q")
{
break;
}
wordList.push_back(word);
}
cout << "input word for check, (q) exits" << endl;
while(cin >> word)
{
if (word == "q")
{
break;
}
iter = find(wordList.begin(), wordList.end(), word);
if (iter != wordList.end())
{
cout << '\a';
}
}
wordList.clear();
return 0;
}
简单实现 =-=

C++ 的容器很容易实现，楼上++
