A character may refer to any of the following:

Letter A representing a character.

1. Sometimes abbreviated as char, a character is a single visual object used to represent text, numbers, or symbols.

For example, the letter "A" is a single character. With a computer, one character is equal to one byte, which is 8 bits. A computer can understand a character with ASCII, which defines each character as a number that is 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 is not supported by the program or operating system. For example, you may get this error when trying to use a non-alphanumeric character or a character with an accent.

Tip

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