The input-output function, like printf() scanf(), getchar(), putchar(), gets(), puts() are known as console oriented I/O functions, which always use keyboard for input device. While using these library functions, the entire data is lost when either the program is terminated or the computer is turned off. At the same time, it is cumbersome and time-consuming to handle a large volume of data through the keyboard. It takes a lot of time to enter the entire data. If the user makes a mistake while entering the data, he/she has to start from the beginning again.
