➢ Input/ Output in C++ :- C++ comes with libraries which provides us many ways for performing input and output. In C++. input and output is performed in the form of sequence of bytes or more commonly known as streams. ● Input Stream: If the direction of flow of bytes is from device(for example: Keyboard) to the main memory then this process is called input. ● Output Stream: If the direction of flow of bytes is opposite, i.e. from main memory to device(display screen ) then this process is called output. ● Header files available in C++ for Input – Output operation are: • iostream: iostream stands for standard input output stream. This header file contains definitions to objects like cin, cout, cerr etc. • fstream: This header file mainly describes the file stream. This header file is used to handle the data being read from a file as input or data being written into the file as output. ...
