An important component to understanding the C programming language is having a proper understanding of the formatting of the input and output streams. Input operations involve data that flows from the input device such as a keyboard or hard drive to the main memory. Output operations involve data that flows from main memory out to a device such as the screen, a printer, or the hard drive. How you want your output displayed or formatted on the screen depends on the conversion specifiers you use in your program.
