C90 Comment Style Trick

C90 does not have // style comments, we can differentiate C90 from C99, C11 and C++: #include <stdio.h> int main() { int i = 2 /**/ /2 ; printf( "%d\n", i ); // 1 in C90 // 2 in C99, C11 and C++ return 0; }

A C code snippet uses the block comment /**/ and a line break to make the expression parse differently in C90 versus C99, C11, and C++. The joke is aimed at programmers who enjoy obscure language-standard trivia and is shared as a nerdy, absurd coding reaction.
