Question

我有一个问题从一个文件中读取，该文件中有空格分隔的单词，并且随机添加新行。这是我的代码：

vector<string> _vecIgnoreWords;
vector<string> _vecHungerGames;

void readTextFile(char *fileNameHungerGames, vector<string>& _vecHungerGames){
    ifstream fileInHungerGames;
    string newline;

    fileInHungerGames.open(fileNameHungerGames);
    if(fileInHungerGames.is_open()){
        while(getline(fileInHungerGames, newline)){
            stringstream iss(newline);
            while(iss){
                iss >> newline;
                if(!(isCommonWord(newline, _vecIgnoreWords))){
                    _vecHungerGames.push_back(newline);
                    cout << newline << endl;
                }
            }
        }

        fileInHungerGames.close();  
    }

主要电话：

string fileName = argv[2];
string fileNameIgnore = argv[3];
char* p = new char[fileNameIgnore.length() + 1];
memcpy(p, fileNameIgnore.c_str(), fileNameIgnore.length()+1);
getStopWords(p, _vecIgnoreWords);
char* hungergamesfile_ = new char[fileName.length() + 1];
memcpy(hungergamesfile_, fileName.c_str(), fileName.length()+1);
readTextFile(hungergamesfile_, _vecHungerGames);

停止词无效：

void getStopWords(char *ignoreWordFileName, vector<string>& _vecIgnoreWords){
    ifstream fileIgnore;
    string line;
    fileIgnore.open(ignoreWordFileName);
    if(fileIgnore.is_open()){
        while(getline(fileIgnore, line)){
            _vecIgnoreWords.push_back(line);
        }
    }
    fileIgnore.close();
    return;
}

我目前的问题是此代码的输出结果如下：

bread
is
is 
slipping
away 

take

我不确定为什么我在使用字符串流时会重复（is is）和空行？

我的输出应该如下：

bread 
is 
slipping
away 
from 
me

同样稍微不那么重要但是我的while循环循环次数太多了，这就是为什么我有if(_vecHungerGames.size() == 7682)有没有办法从循环中修复这个循环太多了？

文件示例：

bread is 
slipping away from me 
i take his hand holding on tightly preparing for the

尝试更像这样的事情：

#include <iostream>
#include <vector>
#include <string>
#include <fstream>
#include <sstream>

std::vector<std::string> _vecIgnoreWords;
std::vector<std::string> _vecHungerGames;

void getStopWords(const char *filename, std::vector<std::string>& output)
{
    std::ifstream file(fileName);
    std::string s;

    while (std::getline(file, s))
        output.push_back(s);
}

void readTextFile(const char *filename, std::vector<std::string>& output)
{
    std::ifstream file(fileName);
    std::string s;

    while (file >> s)
    {
        if (!isCommonWord(s, _vecIgnoreWords))
        {
            output.push_back(s);
            std::cout << s << std::endl;
        }
    }
}

int main()
{
    getStopWords(argv[3], _vecIgnoreWords);
    readTextFile(argv[2], _vecHungerGames);

    // use _vecHungerGames as needed...

    return 0;
}

C ++从文件读入，用空格和新行分隔的单词
