What is the function on endl in c plus plus?
std::endl means end line, and is typically used to insert a new-line character in an output stream using the insertion operator (<<). This is really no different to inserting the '\n' character code to the output stream, however it also serves to flush the output buffer by writing all unwritten characters to the output stream. When used as a global function, std:endl(ostream& OS) can be used to insert a new-line character and flush the given output stream. The return value is a reference to the output stream itself thus it can be used in compound statements that make use of the return value.
Writes the current line terminator to the standard output stream?
NET Framework Class Library writes the specified data, followed by the current line terminator, to the standard output stream.
What are input output streams in c plus plus?
The term stream is a generic abstraction that says nothing about the implementation. However, if we use the analogy that gave it its name, a stream of water, we can better understand how a stream works. A water stream allows water to flow from one point to another in one direction only (downstream, with the flow of the current). If we were to throw a stick into the water, it would be carried downstream by the water where it could then be extracted. Sticks can be inserted or extracted automatically by devices, thus allowing information to pass between those devices.A file stream is a stream that is associated with a device representing a file. If the file is upstream then we can use the stream to extract information from the file. When we extract information from a stream, that stream is known as an input stream; it provides us with information. Conversely, if the file were downstream then we can use the stream to insert information into the file. When we insert information into a stream, that stream is known as an output stream; it carries information away from us.An input/output stream is one where we can both insert and extract information. An input/output file stream is a typical example: we can extract data from the file associated with the stream, process the data (modify it in some way), and then insert the modified data back into the same file. To implement an input/output stream, we simply use two streams associated with the same device: one specifically for input operations, the other specifically for output operations. This implementation detail is hidden from the user, so the stream appears to be a bi-directional stream as far as the user is concerned.
What are filestream classes in c plus plus?
The file stream classes (ifstream and ofstream) are derivatives of the I/O stream classes (istream and ostream) that are specific to file input and output.
What is standard input and output error file?
The C standard library provides stderr as the standard error file. It is an output file, much like stdout, except it cannot be redirected via the command line. By default, error messages via stderr are output to the console, the same as the undirected stdout. However, the programmer may choose to redirect stderr to a disk file or allow the user to choose a location via command line switches. Although error messages can also be output to stdout (or indeed to any output stream), it is best to keep error messages separate from the standard output stream. For instance, the user may choose to redirect standard output to a disk file or to the input stream of another program, while error messages are directed to the console.

What type of output does an S PDIF port provide?
Digital audio stream
What is the use of printf and scanf function?
Printf prints something to the standard output stream, and scanf inputs something from the standard input stream.
What is stream operator in c plus plus?
There are two stream operators: << (insert or put) and >> (extract or get). Output streams implement the insertion operator, input streams implement the extraction operator and input/output streams implement both operators.
What Is Out in java?
System.out is the standard output stream, i.e. the console running the java program nngvhnhbm
Explain the input stream and output stream class hirerarchies with suitable diagrams?
The diagrams can be made off the description that you are able to give. Make them both as detailed as you are able to.
What is seekp in oop?
seekp sets the put pointer in an output stream -- the point where the next insert will occur.

Which stream functions in c plus plus control the formatting of input and output values of a class?
None of them. To control the formatting of your classes, you must overload the stream insertion and extraction operators.
