Character literal

A character literal is the representation of a character value within the source code of a computer program. Languages that have a character data type generally have character literals; these include C, C++, Java, and Visual Basic, but not Python. A common convention is to use a single quote (') for character literals and a double quote (") for string literals. For example, 'a' indicates the single character a while "a" indicates the string a of length 1.
