Hi guys

What is the best way to achieve multiline strings such as:

puts("
<html>
</html>
");

without using \ at the end or "" on each line?

thanks!

Write your own preprocessor to convert newlines to \ inside strings or
find a compiler that allows multi-line strings in its grammar as an
extension. Otherwise it can't be done in standard C:

string-literal:
" s-char-sequence-opt "
L" s-char-sequence-opt "
s-char-sequence:
s-char
s-char-sequence s-char
s-char:
any member of the source character set except the
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
double-quote ", backslash \, or
new-line character
^^^^^^^^^^^^^^^^^^
escape-sequence

puts("<html>" "blah blah" "</html>\n");

is identical if effect to:

puts("<html>blah blah</html>\n");

i.e. adjacent strings (no commas etc) are simply concatentated.
You can spread them over multipl lines too:

puts("<html>"
"blah blah"
"</html>\n");
