Stack of pointers to functions that are called when certain events occur. The second function extracts up to n - 1elements and stores them in the array beginning at s. The state flags for which a failure exception is thrown. basicistream& getline(chartype s, streamsize n) basicistream& getline(chartype s, streamsize n, chartype delim) The first of these unformatted input functionsreturns getline(s, n, widen(' ')). Individual values may be obtained by calling good, eof, fail and bad. ![]() The locale object used by the function for formatted input/output operations affected by localization properties.Ĭharacter to pad a formatted field up to the field width ( width). ![]() Width of the next formatted element to insert.ĭecimal precision for the next floating-point value inserted. Objects of these classes keep a set of internal fields inherited from ios_base, ios and istream:Ī set of internal flags that affect how certain input/output operations are interpreted or generated. The class relies on a single streambuf object for both the input and output operations. This class inherits all members from its two parent classes istream and ostream, thus being able to perform both input and output operations. The getline () function extracts characters from the input stream and appends it to the string object until the delimiting character is encountered. This is an instantiation of basic_iostream with the following template parameters: The C++ getline () is a standard library function that is used to read a string or a line from an input stream.
