Alphanumeric Character Definition
A character that is either a letter (A-Z, a-z) or a digit (0-9) is referred to as an alphanumeric character. Numerous scenarios call for the use of alphanumeric characters, such as when creating passwords, identification numbers, and other kinds of codes. Alphanumeric characters are a fundamental component of many programming languages and data formats, and they are frequently used in computing to represent text and other types of data.
The words “alpha” and “numeric,” which both mean “letters” and “numbers,” are combined to form the term “alphanumeric.” They refer to any character that is either a letter or a number when used collectively.
