Question

How to directly read a string in std::string from a file in C++?

The examples I saw all use char xx[200];

Just use `std::getline` from the `` header. If you instead use the `>>` operator you will get the next whitespace-separated "word", not the next line. — Cheers and hth. - Alf, Aug 31 '17 at 03:14
What kind of string do you want to read exactly? A single word? A whole line? The whole file? Each one is approached differently, so please clarify your requirement. — Remy Lebeau, Aug 31 '17 at 08:35

The <string> realized a >> operator, that can read a string into std::string directly from std::istream.
