char literalssuggest change
char literals are defined by wrapping the value with single-quotes
char c = 'h';
Character literals may contain escape sequences. See String Escape Sequences
A character literal must be exactly one character long (after all escape sequences have been evaluated). Empty character literals are not valid. The default character (returned by
new char()) is
'\0', or the NULL character (not to be confused with the
null literal and null references).
