What is stream explain the stream classes for console I O operation?

The C++ I/O system contains a hierarchy of classes that are used to define various streams to deal with both the console and disk files. These classes are called stream classes. The hierarchy of stream classes used for input and output operations is with the console unit.

What are the console I O function?

Console I/O functions: These functions allow us to receive input from the input devices like keyboard and provide output to the output devices like the Visual Display Unit. File I/O functions: These functions allow us to access the hard disk or floppy disk to perform input and output.

What is the difference between ofstream and ifstream?

ifstream is an input file stream. It is a special kind of an istream that reads in data from a data file. ofstream is an output file stream. It is a special kind of ostream that writes data out to a data file.

What are stream classes?

The Stream class defines objects which accepts a sequence of characters. Streams may also have an output in which case multiple stream objects can be cascaded to build a stream pipe where the output of a stream is directed into the input of the next stream object “down the line”.

What is meant by IO stream in C++?

In C++ input and output are performed in the form of a sequence of bytes or more commonly known as streams. Input Stream: If the direction of flow of bytes is from the device(for example, Keyboard) to the main memory then this process is called input.

What does stream mean in C++?

In C++ stream refers to the stream of characters that are transferred between the program thread and i/o. Stream classes in C++ are used to input and output operations on files and io devices. These classes have specific features and to handle input and output of the program. The iostream.

What are the two categories of console I O function?

There are two types of a console I/O functions: Formatted input-output function. Unformatted input-output function.

What is C++ console?

A modern console consists of the keyboard and a window on a computer screen. cin (console in), cout (console out), and cerr (console error) are stream objects that become part of every C++ program. The console objects channel streams of bytes to and from running programs.

What are the C++ stream classes?

Classes associated with the C++ stream include ios class, istream class, and ostream class. Class ios is indirectly inherited from the base class involving iostream class using istream class and ostream class which is declared virtually.

What is Stream class example?

Some important Byte stream classes.

What are streams in C++? What are the advantages of C++ I O streams?

The I/O stream classes in the Standard C++ Library have the following advantages:

• The input ( >> ) operator and output ( << ) operator are typesafe. These operators are easier to use than scanf() and printf() .
• You can overload the input and output operators to define input and output for your own types and classes.

What is file and stream I/O in Windows?

File and Stream I/O. File and stream I/O (input/output) refers to the transfer of data either to or from a storage medium. In the .NET Framework, the System.IO namespaces contain types that enable reading and writing, both synchronously and asynchronously, on data streams and files.

What is I/O stream in Java?

Java provides I/O Streams to read and write data where, a Stream represents an input source or an output destination which could be a file, i/o devise, other program etc. In general, a Stream will be an input stream or, an output stream. InputStream − This is used to read data from a source.

What is the difference between input stream and output stream?

In general, a Stream will be an input stream or, an output stream. InputStream − This is used to read data from a source. OutputStream − This is used to write data to a destination. Based on the data they handle there are two types of streams −. Byte Streams − These handle data in bytes (8 bits) i.e., the byte stream classes read/write data

What is the difference between a file and a stream?

When you work with files, you work with directory paths, disk storage, and file and directory names. In contrast, a stream is a sequence of bytes that you can use to read from and write to a backing store, which can be one of several storage mediums (for example, disks or memory).
