char

Description

A data type used to store a character value. Character literals are written in single quotes, like this: A (for multiple characters - strings - use double quotes: "ABC").

Characters are stored as numbers however. You can see the specific encoding in the ASCII chart. This means that it is possible to do arithmetic on characters, in which the ASCII value of the character is used (e.g. A + 1 has the value 66, since the ASCII value of the capital letter A is 65). See
