What is text file and binary file in c
Thus, we see that each digit in the file is treated as a character in itself and occupies more space than necessary. So, if we have a lot of numerical data then using a text file will not be very memory efficient but still the syntax used depends on our usage i. This problem can be solved by using binary files. The, using the function fread or fwrite we can easily store the data in the binary form which shall use only 4 bytes for storing the integer data.
Another way the text mode and the binary mode can be distinguished is on the basis of the representation of the end-of-file EOF. This character when encountered returns the EOF signal to the program. This is not the case in binary mode.
In the binary mode , we do not have any special character to signify the EOF. It keeps track with the help of the number of characters present in the directory entry of the file.

Many other binary file types include sections of readable text as well. Therefore, it may be possible to find out some information about an unknown binary file type by opening it in a text editor. Binary files often contain headers, which are bytes of data at the beginning of a file that identifies the file's contents.
Headers often include the file type and other descriptive information. If a file has invalid header information, software programs may not open the file or they may report that the file is corrupted. Text files are more restrictive than binary files since they can only contain textual data. However, unlike binary files, they are less likely to become corrupted.
While a small error in a binary file may make it unreadable, a small error in a text file may simply show up once the file has been opened. This is one of reasons Microsoft switched to a compressed text-based XML format for the Office file types.
Text files may be saved in either a plain text. TXT format and rich text. A typical plain text file contains several lines of text that are each followed by an End-of-Line EOL character. Rich text files use a similar file structure, but may also include text styles, such as bold and italics, as well as page formatting information.
Both plain text and rich text files include a character encoding characterencoding scheme that determines how the characters are interpreted and what characters can be displayed. Since text files use a simple, standard format, many programs are capable of reading and editing text files. If you come across an unknown file type, first look up the file extension on FileInfo. If the file does not have an extension or you are unable to locate the file type, you can attempt to open the file in a text editor.
If the file opens and displays fully readable text, it is a text file, which you have successfully opened. If the file opens and displays mostly garbled text, it is a binary file.
