我有一个包含字符串的文件,例如

你好,我叫乔

你好吗?

好吗

我试图按原样输出该文件,但是我的程序将其输出为“HellomynameisJoeHowAreyouDoing?Goodyou?”。我在空格和换行时遇到问题。

int main (int argc, char* argv[])

{
index_table table1;

string word;
ifstream fileo;

    fileo.open(argv[1]); //where this is the name of the file that is opened

    vector<string> line;

    while (fileo >> word){
        line.push_back(word);
    }
    cout << word_table << endl;
    for (int i=0; i < line.size(); i++)
    {
        if (find(line.begin(), line.end(), "\n") !=line.end())
            cout << "ERRROR\n"; //My attempt at getting rid of new lines. Not working though.
        cout << line[i];
    }
    fileo.close();

返回0;

最佳答案

只需使用: std::getline

while (std::getline(fileo, word))
{
        line.push_back(word);
}

然后,
for (int i=0; i < line.size(); i++)
{
  std::cout<<line[i]<<std::endl;
}

或简单地:
std::copy(line.begin(), line.end(),
           std::ostream_iterator<std::string>(std::cout, "\n") );

//With C++11
for(const auto &l:line)
  std::cout<<l<<std::endl;
