Input Validation. In practice, program users don't always follow instructions, and you can get a mismatch between what a program expects as input and what it actually gets. Such conditions can cause a program to fail. However, often you can anticipate likely input errors, and, with some extra programming effort, have a program detect and work around them. Suppose, for example, that you're C Input Output (I/O) In this tutorial, you will learn to use scanf() function to take input from the user, and printf() function to display output to the user.
