WebFeb 14, 2024 · std::getline is basically used to read a std::string from a stream, until a delimiter is found. In most cases, and that is also a default argument, the delimiter is '\n'.

WebUse std::getline () to read the whole line into a string first. Then create a stringstream from the input string. Finally use a istream_iterator to iterate over the individual tokens. Note that this method will fail at the first input that is not an integer. For example if the use inputs: " 1 2 ab 3" then your vector will contain {1,2}.
