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:
“They who know of no purer sources of truth, who have traced up its stream no higher, stand, and wisely stand, by the Bible and the Constitution, and drink at it there with reverence and humility; but they who behold where it comes trickling into this lake or that pool, gird up their loins once more, and continue their pilgrimage toward its fountain-head.”
—Henry David Thoreau (1817–1862)
“We see which way the stream of time doth run.”
—William Shakespeare (1564–1616)
