ascii code value of 99

What is the ascii code for

The details are as follows.

The ASCII value of a space is 32; the ASCII values of the numbers 0 to 9 are 48 to 57; the ASCII values of the capital letters “A” to “Z” are 65 to 90; the ASCII values of the lowercase letters “a” to “z” are 97 to 12; the ASCII values of the letters “a” to “z” are 97 to 12; and the ASCII values of the letters “a” to “z” are 97 to 12. The ASCII values for “a” to “z” are 97 to 122.

ASCII (( AmericanStandardCodeforInformationInterchange):American Standard Code for Information Interchange) is a system of computer coding based on the Latin alphabet, primarily used to display modern English and other Western European languages. It is the most common standard for information exchange and is equivalent to the international standard ISO/IEC 646.ASCII was first published as a standard in 1967, and last updated in 1986, with a total of 128 characters defined to date.

What are the ASCII codes for characters A through Z?

①The ASCII codes for uppercase characters A to Z are 065 to 090, character plus one, code plus one

②The ASCII codes for lowercase characters a to z are 097 to 122, still character plus one, code plus one

The following chart shows the ASCII code correspondences of common characters

Extended Information

32 to 126 (total 95) are characters (32 is a space), of which 48 to 57 are the ten Arabic numerals from 0 to 9.

65 to 90 are 26 uppercase letters of the alphabet, 97 to 122 are 26 lowercase letters of the alphabet, and the rest are some punctuation marks, arithmetic symbols and so on.

Also note that in standard ASCII, the highest bit (b7) is used as the parity bit. The so-called parity check is a method used to check for errors in the code transmission process, and is generally divided into two types of checksums: odd and even.

Odd parity rule: the correct code in a byte of the number of 1 must be odd, if not odd, then in the highest bit b7 add 1; even parity rule: the correct code in a byte of the number of 1 must be even, if not even, then in the highest bit b7 add 1.

Keyboard keys corresponding to the ASCII code value (including the mouse and keyboard all the keys)

Keyboard and mouse keys corresponding to the ASCII code value is as follows:

This is the keyboard and the mouse on the keys corresponding to the ASCII code, some of the support for macro programming of the keyboard and the mouse above the keys do not have an exclusive ASCII code, the specific corresponding to the ASCII code depends on the programming object. The ASCII code for each key depends on the object being programmed.

Expanded information:

These are the ASCII codes for the keys on some keyboards and mice that support macro programming.

Comparison according to the corresponding ASCII value,c is bigger than b, t is bigger than R, A is bigger than a, comma is bigger than space, which is wrong?

Where there is an error, the comma is smaller than a space, not larger than a space.

Characters are compared according to their corresponding ASCII value size. According to the ASCII code table, the character c has an ASCII code value of 99, while the character b has an ASCII code value of 98, so c is larger than b. Similarly, the character t has an ASCII code value of 116, while the character R has an ASCII code value of 82, therefore t is larger than R.

However, characters A and a have ASCII code values of 65 and 97, respectively, so a is greater than A, not A is greater than a.

Finally, the comma has an ASCII value of 44, while the space has an ASCII value of 32, so the comma is smaller than the space, not larger than the space.
