C ++从文件中读取用空格和换行符分隔的单词[重复]

Question

我在从包含以空格分隔的单词和随机换行的文件中读取时遇到问题。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();  
    }

main 中的调用：

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);

停用词无效：

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;
}

我目前的问题是我的这段代码的输出结果如下：

bread
is
is 
slipping
away 

take

我不确定为什么在使用字符串流时会出现重复（is is）和空行？

我的输出应该是这样的：

bread 
is 
slipping
away 
from 
me 

同样不那么重要，但我的 while 循环循环次数过多，这就是为什么我有 if(_vecHungerGames.size() == 7682) 有没有办法解决这个循环循环次数过多的问题？

文件示例：

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

试试这样的：

#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;
}
