c++ - c++中使用getline()时如何判断是否是EOF？

Question

string s;
getline(cin,s);

while (HOW TO WRITE IT HERE?)
{
    inputs.push_back(s);    
    getline(cin,s);
}

Answer 1

由于我今天懒得给出完整的答案，所以我就把真正有用的 bot in ##c++ on Freenode 说的话贴出来吧:

Using "while (!stream.eof()) {}" is almost certainly wrong. Use the stream's state as the tested value instead: while (std::getline(stream, str)) {}. For further explanation see http://www.parashift.com/c++-faq-lite/input-output.html#faq-15.5

换句话说，你的代码应该是

string s;

while (getline(cin, s))
{
    inputs.push_back(s);    
}
