Input - Output Functions in C language
Basics of Input/Output Functions in C Language Input and Output (I/O) operations are fundamental in any programming language because they allow a program to interact with users and external devices. In the C language, I/O operations are handled through a set of standard library functions defined in the header file stdio.h (Standard Input Output). These functions help in reading input from the user and displaying output to the screen, files, or other devices. 1. Introduction to I/O in C In C, there are two main types of I/O operations: 1. Input Receiving data from the user or another source (keyboard, file, etc.) 2. Output Displaying or sending data to the user or another destination (screen, file, etc.) C does not have built-in keywords for I/O (like some other languages). Instead, it uses functions provided by the standard library. 2. Header File for I/O Functions All standard input/output functions are declared in: #include <stdio.h> This header file must b...
