How to Create A Data File?

A data file should be created before it can be processed. A stream-oriented data file is able to be created in two ways. One is to create the file straight, using a word processor or a text editor and the other is to write a program that enters information into the computer and then writes it out to the data file. Unformatted data files are able to only be created with such specially written programs.

While creating a new data file with a specially written program the standard approach is to enter the information from the keyboard and then write it out to the data file. If the data file consists of individual characters the library functions putc and getchar be able to be used to enter the data from the keyboard and to write it out to the data file.
