Basic Input/Output

Preview
Until now, the example programs of previous sections provided very little interaction with the user, if any at all. Using the standard input and output library, we will be able to interact with the user by printing messages on the screen and getting the user's input from the keyboard.
C++ uses a convenient abstraction called streams to perform input and output operations in sequential media such as the screen or the keyboard. A stream is an object where a program can either insert or extract characters to/from it. We do not really need to care about many specifications about the physical media associated with the stream - we only need to know it will accept or provide characters sequentially.
The standard C++ library includes the header file iostream, where the standard input and output stream objects are declared.

Data Input/Output

Preview
The values and expressions used in C++ are displayed using the cout extractor. To make the displaying of data more realistic, the cout is configured to handle or format data to any desired result. While the cout (as a class) is defined in the iostream file, some other files provide other extensive techniques for displaying data to the console. The C language also is equipped with other formatting functions used for the same purpose. The ability to create a program made of mixed C and C++ language enhances these formatting possibilities.
