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

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

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

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.
See here may, a lot of people wonder ~. So why $ I am a variable such Chinese can also be a variable name. In PHP, Chinese can do variable names (can be
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
The problem of character encoding seems to be very small, often overlooked by technical staff, but it can easily lead to some puzzling problems. Here is a summary of the character encoding of some of the popular knowledge, I hope to be helpful to everyone.I still have to start with the ASCII code.Speaking of character encoding, we have to say a brief history of ASCII code. Computers were invented at the out
