Sets the position of the next character to be extracted from the input stream. Internally, the function accesses the input sequence by first constructing a sentry object (with noskipws set to true).
WebInput/output stream class to operate on files. Objects of this class maintain a filebuf object as their internal stream buffer, which performs input/output operations on the file they are associated with (if any). File streams are associated with files either on construction, or by calling member open. This is an instantiation of basic_fstream with the following … WebThe class template basic_istream provides support for high level input operations on character streams. The supported operations include formatted input (e.g. integer values …
WebA stream buffer is an object in charge of performing the reading and writing operations of the stream object it is associated with: the stream delegates all such operations to its associated stream buffer object, which is an intermediary between the stream and its controlled input and output sequences. All stream objects, no matter whether buffered or unbuffered, … WebConstructs an ifstream object: (1) default constructor Constructs an ifstream object that is not associated with any file. Internally, its istream base constructor is passed a pointer to a newly constructed filebuf object (the internal file stream buffer). (2) initialization constructor Constructs an ifstream object, initially associated with the file identified by its first …
WebAug 3, 2024 · istream & getline (istream & input_stream, string & output, char delim); What this says is that getline() takes an input stream, and writes it to output. Delimiters can be optionally specified using delim. This also returns a reference to the same input stream, but for most cases, we don’t need this handle. Using std::getline() to read from ...

The OP's question calls close() explicitly, so it makes sense to check is_open() to bypass the rest of the code if open() fails. Yes, the ifstream destructor closes the file, but not until the ifstream goes out of scope. Users are allowed to explicitly close() before that time.
