Talk:cpp/preprocessor/conditional

Looking at the C++ standard, it seems that there is an operator "defined" that can be used in preprocessor conditionals that is not mentioned here. It is defined in 16.1.1

it's right on this page where it says "If the expression contains unary operators in form defined identifier or defined (identifier)". Could be formatted better, pehaps. --Cubbi (talk) 14:26, 5 December 2016 (PST)
