C programming tutorial for absolute beginners lesson 5 - Get User Input in C programming

In C, user input is typically obtained using functions from the stdio.h library. The most common function for this purpose is scanf(), which reads formatted input from the standard input stream (usually the keyboard). To use scanf(), you specify a format string that describes the expected input, followed by the addresses of variables where the input will be stored. For example, scanf("%d", &number) reads an integer into the variable 'number'. Other useful functions include fgets() for reading strings (including spaces) and getchar() for reading single characters. It's important to handle potential input errors and buffer overflows when using these functions to ensure robust and secure code.
