char Constants

A char constant is written with single quotes (') like 'A' or 'z'. The char constant 'A' is really just a synonym for the ordinary integer value 65 which is the ASCII value for 4

 uppercase 'A'. There are special case char constants, such as '\t' for tab, for characters

which are not convenient to type on a keyboard.


'A'    uppercase 'A' character


'\n'   newline character


'\t'   tab character


'\0'   the "null" character -- integer value 0 (different from the char digit '0')


'\012' the character with value 12 in octal, which is decimal 10
