What’s the difference between getline and std::istream::operator>>()?

by

The difference is thatstd::getline — as the name suggests — reads a line from the given input stream (which could be, well, std::cin) and operator>> reads a word1.

That is, std::getline reads till a newline is found and operator>> reads till a space (as defined by std::isspace) and is found. Both remove their respective delimiter from the stream but don’t put it in the output buffer.

1. Note that >> can also read numbers — int, short, float, char, etc.
