If single or double quote characters are used, then you also have the option, a la ANSI-C syntax, of implicitly concatenating a series of them together, with intervening white space ignored.
NB You cannot use directives to alter the string content. That is,
str = "fumble" #ifdef LATER "stumble" #endif ;
will result in a syntax error. The preprocessing directives are not carried out by the C preprocessor. However,
str = '"fumble\n" #ifdef LATER " stumble\n" #endif ';

and ‘#endif’ in the string. But it may also wreak
havoc with the definition processing directives. The hash
characters in the first column should be disambiguated with

"fumble\n#ifdef LATER....
