|
|
followed by that character. The same escapes apply to characters as
|
|
to strings. So if you want to write the character backslash, you
|
|
must write <kbd>'\\</kbd> where the first <code>\</code> escapes the second
|
|
<code>\</code>. 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. <span class="command">as</span> assumes your character code is ASCII:
|
|
<kbd>'A</kbd> means 65, <kbd>'B</kbd> means 66, and so on.
