Binary Vs Text File in C - Programming Techniques
From our point of view, each file is just a series of bytes.In general every file is a binary file, but if the data in it contains only text (letter, numbers and other symbols one would use in writing, and if it consists of lines, then we consider it a text file.(I am going to simplify here a bit for clarity and for now assume that the files are only use ASCII characters.) When you open a text file with Notepad or some other, simple text editor you will see several lines of text. Metatrader 4 otc. The file on the disk on the other hand isn't broken up to such lines. When you open the file using Notepad, it translates each number to a visual representation.For example if it encounters the number 97, it will show the letter a. The reason that you see several lines in your editor is that some of the bytes in the file, that are called newlines, are actually instructions to the editor to go to the beginning of next line.Thus the character that was in the file after the newline character will be displayed in the next line.

The mode parameter is usually left out when dealing with text files, but there are. Forex bank reports. If you have ever seen a Typewriter, you will remember, in order to go to the next line, the user had to pull a handle towards the beginning of the line.(Usually to the left side of the paper.) This movement first pushed the "carriage" to the beginning of the paper and when it arrived to the beginning (and got stuck), further pulling of the handle turning the paper a bit so the carriage would point to the next line. That is, they used two operations carriage return, pushing the "carriage" to the beginning of the paper and line feed - going to the next line.(Image from Wikipedia) Therefore on MS Windows, a newline is represented by two characters: ) to represent a newline.(I learned programming on a HT-1080Z which was a TRS-80 clone and later switched to a ZX Spectrum.) Wikipedia has even more to say about newline.

A text file is simply made of readable text characters. printed to the screen through the cout object; A binary file contains unformatted data, saved in its raw memory format. Therefore people have invented other Encodings, besides ASCII.Without going into the details, each encoding is a mapping between numbers that can be saved in a computer file and "drawings" that should be displayed on the screen.Remember, even in ASCII, you don't have a letter encoding, or in any of the ASCII-based or ASCII-compatible encodings, such as Latin1 or UTF8.
File I/O operations take place in one of two translation modes, text or binary, depending on the mode in which the file is opened. Data files are usually processed in.

As Unicode currently includes more than 110,000 characters it cannot be represented in one byte which can hold only numbers between 0 and 255.So in UTF-8, every character is represented by 1 to 4 bytes.If you open a file that was written using the UTF-8 encoding, with a tool that can only handle ASCII characters, you will see lots of "garbage".

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are.All files are binary; the data within them is a binary representation of some information. If you have to store a large amount of text then the file will contain the binary representation of that text. The difference between a "binary file" and a "text file" is that creating the latter involves converting data to a text form before saving it.
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.A Microsoft word file is a binary file as besides the actual text, it also contains various characters representing font size and color.
