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
to ensure the correct information exchange between human and equipment, equipment and computer, people compiled a unified information exchange code, this is the ASCII code table, its full name is "American Information Interchange Standard code".

The ASCII code can be roughly divided into three parts.The first part is ASCII non-printable control characters;The second part is: ASCII printing characters;The third part is: Extended
the UTF-8 specified can be a byte to represent all the characters ASCII code, to avoid unnecessary space waste.Out of the above several common coding, there are many other codes, different codes specify the rules are different, but basically all the ASCII is compatible with processing, it can be said that ASCII is the most basic, this section is to discuss the

The so-called ASCII and 16 binary are just conceptual things that are all binary in the computerThe conversion should be the output of the conversion, the same number, in the computer memory is the same, but the output is not the sameASCII is the encoding of characters, almost the encoding of characters on the keyboard. The following is an ASCII and 16-binary table

Complete 8-bit ASCII two-dimensional table
ASCII and American Standard Code for information interchange read as "astkey", which defines the English letters or the same result and meaning represented by the 127 numbers ranging from 0 to one hundred and twenty-eight. Because only seven digits (BIT) can be used to represent numbers from 0 to 127, most computers use
The value range of the ASCII code is 0 ~ 127, which can be expressed in 7 bits. C LanguagecharThe variable size is defined as one byte. If the ASCII code is stored, only seven characters are used, and the value is 0. The following is an ascii code table:

Odd check rules: The correct code in one byte of the number of 1 must be odd, if not odd, the highest bit B7 Tim 1; Parity rule: The correct code in a byte of 1 must be an even number, if not even, the highest bit B7 add 1.Report:ASCII table
