null character Last modified: Sunday, September 01, 1996
A character that has all its bits set to 0. A null character, therefore, has a numeric value of 0, but it has a special meaning when interpreted as text. In some programming languages, notably C, a null character is used to mark the end of a character string. In database and spreadsheet applications, null characters are often used as padding and are displayed as spaces.
