ASCII (American Standard Code for Information Interchange, American Information Interchange standard codes) is a computer coding system based on the Latin alphabet. It is mainly used to display modern English and other Western European languages. It is the most common single byte coding system today, and is equivalent to international standard ISO/IEC 646. The following is the ASCII code table, I hope to he
line. So, there was a disagreement.Unix system, the end of each line only "
dos and Windows use carriage return + newline cr/lf to represent the next line,
Unix/linux uses the newline character LF to indicate the next line,
the Mac OS system uses a carriage return CR to represent the next line.
The CR symbol ' \ r ' indicates that the decimal ASCII code is 13 and the hexadecimal code is 0x0d;
lf using the ' \ n ' notation, the

I have been idle for the past two days. I think it is interesting to display the image content in ASCII code, so I tried to write it myself, I found it online to know that it was still an art-ASCII art !!
I am also tied to art ~
In this case, the image content is displayed in ASCII code. Different characters are used to represent the gray level, so as to distingu

With the rapid development of computers, many people begin to learn about Linux and learn how to learn Linux commands well. To learn about Linux, you may have knowledge about the Linux Command OD. Here we will introduce the Linux Command OD application method.
Linux Command: OD
Example: OD-C hello
Linux Command: OD
Od commandUsers usually use the OD command to view the content of files in special form
In fact, it is very simple to use the ASCIIEncoding class to convert each other, below I provide two ways to look at the big one1. Character representable ASCII code Public Static intASC (stringcharacter) { if(character. Length = =1) {System.Text.ASCIIEncoding asciiencoding=NewSystem.Text.ASCIIEncoding (); intIntasciicode = (int) asciiencoding.getbytes (character) [0]; return(Intasciicode); } Else { return-1 //length less than 1 } }
[C #] convert character to ASCII code, and convert ASCII code to character
Character to ASCII code:
Public static int ASC (string character){If (character. Length = 1){System. Text. asciiencoding = new system. Text. asciiencoding ();Int intasciicode = (INT) asciiencoding. getbytes (character) [0];Return (intasciicode );}Else{Throw new exception ("charac

Introduction
Most people classify files in two categories: binary files and ASCII
CodingA string is a data type, but a particular string is a coding problem.Because a computer can only handle numbers, if you are working with text, you must convert the text to a number before processing it. The oldest computer was designed with 8 bits (bit) as a byte (byte), so a single word energy-saving representation of the largest integer is 255 (binary 11111111 = decimal 255), if you want to represent a larger integer, you must use more bytes. For example, two bytes can represent the larg

variable naming rules:
1. Variable names are case-sensitive (case-sensitive).
2. Must begin with a letter or underscore.Variable names can consist of letters, numbers, and underscores.
