FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Console I/O functions: These functions allow us to receive input from the input devices like keyboard and provide output to the output devices like the Visual Display Unit.

Detailed explanation-2: -Input and output functions are available in the C language to perform the most common tasks. In every C program, three basic functions take place – accepting of data as input, the processing of data, and the generation of output. The acceptance of data refers to input and the presentation of data refers to the output.

Detailed explanation-3: -The input/output library (io library) is part of the C++ standard library that deals with basic input and output. We’ll use the functionality in this library to get input from the keyboard and output data to the console. The io part of iostream stands for input/output.

Detailed explanation-4: -The program uses console I/O to simply read its “standard input (stdin)"-which might be the keyboard, a file dump, or the output of some other program-and print to its “standard output (stdout)"-which might be the display or printer or another program or a file.

Detailed explanation-5: -It usually means a combination of a display monitor and an input device, usually a keyboard and mouse pair, which allows a user to input commands and receive visual output from a computer or computer system. It can also refer to specialized computers only meant to play video games.
