A character may refer to any of the following:

Letter A representing a character.

1. Sometimes abbreviated as char, a character is a visual object representing text, numbers, or symbols.

For example, the letter "A" is a single character. With a computer, one character is one byte (8 bits). A computer can understand a character with ASCII (American Standard Code for Information Interchange), which defines each character as a number translated to binary. For example, the letter "A" is "65" in ASCII and "01000001" in binary.

Note

An invalid character error may be encountered when a character is used that the program or operating system does not support. For example, you may get this error when using a non-alphanumeric character or a character with an accent.

Tip

See the char definition for a full definition of the char programming term.
