ASCII Chart

The ASCII Chart is a reference that shows the ASCII character set and the decimal and hexadecimal numbers associated with each character.

Control Characters

The first 32 characters (0—31 decimal) in the ASCII chart are control characters. These characters are not printable and are used to control devices such as printers. Also, introduced later on, is the DEL character (127 decimal) which is used to delete a character.
