What data type can be used to hold any single character, including numbers and non-printing characters?

char

Explanation:

In Java and some other programming languages, the data type used to hold a single character including numbers and non-printing characters is char.

Examples of single characters (numbers) that can be held by a char data type are;

(i) 065 - which represent an ASCII code for character 'A' (without quotes)

(ii) 097 which represent an ASCII code for character 'a' (without quotes)

Examples of single characters (non-printing) that can be held by a char data type are;

(i) Non-breaking space

(ii) Tab character

Examples of other single characters that can be held by a char data type are;

(i) 'd' - character d (without quotes)

(ii) 'M' - character m (without quotes)

char

Explanation:

The character data type written as char holds any single character, numbers and non-printing characters. In java and most programming languages, the value of the character must be placed within single quotes. for example

char c = 'd'

char c = '9'

char c = '/t'

Are all valid declarations of a variable c as char and assigned d, then 9 and then used with a non-printing character (tab) with the escape sequence.
