Data File - Stream

A stream is a sequence of bytes. A stream is a general name given to a flow of data. Different streams are used to represent different kinds of data flow. Each stream is associated with a particular class,which contains member functions and definitions for dealing with that particular kind of data flow. The stream that supplies data to the program in known as input stream. It reads the data from the file and hands it over to the program. The stream that receives data from the program is known as output stream. It writes the received data to the file.Following figure illustrates it.

When the main function of your program is invoked, it already has three predefined streams open and available for use. These represent the "standard" input and output channels that have been established for the process.

Famous quotes containing the word stream:

    “Married love is a stream that, after a certain length of time, sinks into the earth and flows underground. Something is there, but one does not know what. Only the vegetation shows that there is still water.”
    —Gerald Branan (1894–1987)

    “In contrast to the flux and muddle of life, art is clarity and enduring presence. In the stream of life, few things are perceived clearly because few things stay put. Every mood or emotion is mixed or diluted by contrary and extraneous elements. The clarity of art—the precise evocation of mood in the novel, or of summer twilight in a painting—is like waking to a bright landscape after a long fitful slumber, or the fragrance of chicken soup after a week of head cold.”
    —Yi-Fu Tuan (b. 1930)

    “The soft engravings which adorn the annuals give no idea of a stream in such a wilderness as this.”
    —Henry David Thoreau (1817–1862)
