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;
