Control Characters: These are used to control the flow of programs, such as newline (\n), carriage return (\r), tab (\t), etc.Numeric Characters: '0' through '9'.Uppercase Letters: 'A' through 'Z'.Lowercase Letters: 'a' through 'z'.Punctuation and Special Characters: Such as !,...
Get ASCII values: It allows you to retrieve the ASCII value of a single character. For example, ASCII('B') will return 66, as 66 is the ASCII value of the uppercase letter 'B'. Sorting: The ASCII() function can be used to sort data based on ASCII values. For instance, we can o...
In the original system of 128 characters, the binary codes were 7 bits long. Today, ASCII uses 8-bit codes to maintain compatibility with modern computers that use 8-bit bytes. The extra bit in these codes is usually set to 0. ASCII characters include uppercase and lowercase letters A ...

The ASCII value of the lowercase letter "h" is 104 in decimal. To remember this, note that the uppercase letter "A" corresponds to 65 and the lowercase letter "a" corresponds to 96. The difference between the ASCII values of "A" and "a" is 32, as there are 26 letters ...
Oh, and by the way: Comparison-wise, uppercase letters are “less” than lowercase. That calculation is based on the character’s ASCII code value. It’s also what thestrcmp()family of functions use to compare two strings. Unlike working with ASCII character codes for characters'0'through'...

ASCII (American Standard Code for Information Interchange) is a 7-bit characters code, with values from 0 to 127. The ASCII code is a subset of UTF-8 code. The ASCII code includes control characters and printable characters: digits, uppercase letters and lowercase letters. ...
The example of it you can see on the ASCII chart above. 95 of the encoded characters can be printed: these are the digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), uppercase letters (A to Z), lowercase letters (a to z) and punctuation symbols. 33 non-printing control codes which...
