Parameters is istream object from which characters are extracted. To extract entire lines of text, see the string overload of global function getline. (see ios_base::iostate for more info on these)Īdditionally, in any of these cases, if the appropriate flag has been set with is's member function ios::exceptions, an exception of type ios_base::failure is thrown. Notice that the istream extraction operations use whitespaces as separators Therefore, this operation will only extract what can be considered a word from the stream. Notice that some eofbit cases will also set failbit. In this case, distr preserves the parameters and internal data it had before the call. The input obtained could not be interpreted as a valid textual representation of an object of this type. The end of the source of characters is reached during its operations. str string object where the extracted content is stored.Ī call to this function may set any of the internal state flags of is if: Notice that the istream extraction operations use whitespaces as separators Therefore, this operation will only extract what can be considered a word from the stream.
This function overloads operator> to behave as described in istream::operator> for c-strings, but applied to string objects.Įach extracted character is appended to the string as if its member push_back was called. Extracts a string from the input stream is, storing the sequence in str, which is overwritten (the previous value of str is replaced).
