  • \$\begingroup\$ You can save some chars by removing the type declaraction, i.e. the void for main and the int for x, and possibly the char for **a (I'm not sure about the last one though). In C the type is default to be int if no type is specified, and you don't necessarily need to return a value for int main. This may produce compilation warning messages, but not errors and the program will still work. \$\endgroup\$ Commented Feb 2, 2014 at 10:54

    \$\begingroup\$ Shaved 17 bytes by removing the pointless #define C(n,...) …. Also, main returns int, not void (and as of C99 it's not required to explicitly "return 0" at the end of main; the implementation implicitly adds it for you). \$\endgroup\$ Commented Feb 3, 2014 at 2:09
  • \$\begingroup\$ @ace Thank you! I had forgotten that types defaults to int i C. But it looks like it's all-or-nothing; you can't have some variables in the call signature use default types while others don't. So I just changed it to main() and hardcode the filename to o instead of passing it to main. Now it's smaller than the Java version :) \$\endgroup\$ Commented Feb 3, 2014 at 2:35
  • \$\begingroup\$ @Quuxplusone Thanks! Did not know that C99 add an implicit return 0 to main if not already there. That was why I choose to (incorrectly) return void instead of int. Since you got rid of the vararg macro, C99 is not required to compile the code anymore. <rant>Which makes it more portable to compilers who's vendors has chosen to not implement C99 [read: Microsoft] :)</rant> \$\endgroup\$ Commented Feb 3, 2014 at 2:45
