Text File and binary file, text file binaryHere we will talk about the standard interfaces for reading and writing text files, binary files, and C language files.
It is binary for physical storage. The key is that the data encodin
1) Introduction to text files and binary filesThe so-called text file stores all characters in the file. For example, a string 123 is stored in the text file in its ASCII form, that is, the ASCII form of each character:31 32 33 is stored in text files for example, for an int
text file uses seven bits in one byte to represent all information, the binary file uses all bits in the bytes. This is the difference between the two. When an object is opened in text or binary mode, what is the difference between the two? In fact, both binary files and
text is read to send a carriage return, line two characters into a character, equivalent to truncated file. But why is it just possible? Because it is possible that the text does not have a connected 45,42 two bytes (45 is the ASCII of CR carriage return, 42 is the ASCII code of the newline character Cl), there is no "truncated" operation, so the content read is
There are many articles on text files and binary files on the Internet, but unfortunately these articles are all compared.. Next I will talk about text files and binary files from multiple perspectives based on the information I have found.

Task:Given a collection of strings that need to be preserved, construct a filter function and apply it to any string s, the function returns a copy of S that contains only the elements in the specified character set.Solution: ImportStringallchars= String.maketrans ("',"')#All chars TabledefMakefilter (Keep): Delchars=allchars.translate (allchars,keep)defThefilter (s):returns.translate (allchars,delchars) #delchars是要

how long the application time is or the universality of the application, ASCII encoded files are incomparable to files in other formats.

From the file encoding method, the file can be divided into ASCII code files and binary code file two kinds.ASCII files are also referred to as text files, which are stored on disk with one byte per character for the corresponding ASCII code. For example, the number 5678 is
The so-called binaries and text files are not different for letters, they are ASCII values that store the letters. Can cause difference is the number and some layout with the symbol format.
A number stores the value of the number in a binary file, and the text file first treats the number as a character amount and converts it to a new digital re-storage
Determine whether a file is a text file or a binary file can help the compression software for different files to select the corresponding algorithm, then how to determine whether a file is text or binary it.
Older versions of PKZIP are used in the following way: If more than 80% of the bytes fall to 7. In the range of

Create a file MyFile.txt in the current directory with read and write access to the file

Create a data flow writer, associating with open files

OverviewThis chapter first introduces the relevant theoretical knowledge of two-fork tree, then gives the detailed implementation of C language. On the learning of binary tree, it is necessary to explain: it is not difficult, not only not difficult, but it is very simple. The first contact with the tree, I also think it seems difficult, and the resulting feeling is mainly due to the binary tree has a lot of
