C++ Input/Output: Streams - Computer Science
Computer Science Dept Va Tech August, 2001 1995-2001 Barnette ND & McQuain WD14. input /OutputIntro Programming in C++C++ input / output : StreamsThe basic data type for I/O in C++ is the stream. C++ incorporates a complex hierarchy of stream types. The most basic stream types are the standard input / output Streams :istream cinbuilt-in input stream variable; by default hooked to keyboardostream coutbuilt-in output stream variable; by default hooked to consoleheader file: <iostream>C++ also supports all the input / output mechanisms that the C language included. However, C++ Streams provide all the input / output capabilities of C, with substantial will exclusively use Streams for input and output of Science Dept Va Tech August, 2001 1995-2001 Barnette ND & McQuain WD24. input /OutputIntro Programming in C++C++ Streams are ObjectsThe input and output Streams , cinand coutare actually C++ objects. Briefly:class:a C++ construct that allows a collection of variables, constants, and functions to be grouped together logically under a single nameobject:a variable of a type that is a class (also often called an instance of the class)For example, istreamis actually a type name for a class.
Computer Science Dept Va Tech August, 2001 ©1995-2001 Barnette ND & McQuain WD 6 4. Input/Output Intro Programming in C++ Input: the Extraction Operator To get information into a file or a program, we need to explicitly instruct the computer to acquire the desired information. One way of accomplishing this in C++ is with the use of an input ...
