推荐答案

我测试了 Kaleb Pederson 的回答，并找到了比他提出的解决方案更简洁的方法(尽管我必须感谢他为我指明了正确的方向):

I tested out Kaleb Pederson's answer, and found a more consise way than the solution he presented (though I have to thank him for pointing me to the right direction):

QTextStream qtin(stdin); 
QString line = qtin.readLine();  // This is how you read the entire line

QString word;
qtin >> word;    // This is how you read a word (separated by space) at a time.

换句话说，您并不真正需要 QFile 作为您的中间人.

In other words, you don't really need QFile as your middleman.
