A single character may be written as a single quote immediately followed by that character. Some backslash escapes apply to characters,
with the same meaning as for strings, plus
for a single quote. So if you want to write the character backslash, you must write '\\
where the first
escapes the second
. As you can see, the quote is an acute accent, not a grave accent. A newline immediately following an acute accent is taken as a literal character and does not count as the end of a statement. The value of a character constant in a numeric expression is the machine's byte-wide
code for that character.
assumes your character code is ASCII: 'A
means 65, 'B
means 66, and so on.
