- Why are there digraphs in C and C++? 4 answers
In one of my courses I've been given this cryptic c code.
%:define BBRACE (
%:define BRACEE )
%:define CCURLY_BRACE {
%:define CURLY_BRACEE }
%:define SEMICOLON ;
%:define COMMA ,
int main BBRACE int argc COMMA char *argv<::> BRACEE CCURLY_BRACE return 1^2^3^4^5^6^7 SEMICOLON CURLY_BRACEE
Its not that complicated but I've never seen %:define ... is there any difference to #define ...? I found nothing about %:online.
Same goes with char *argv<::> but I don't know if this really deserves a second question.
