#define HELPER 0//**/
#define CPLUSPLUS_COMMENTS_SUPPORTED (HELPER+1)
More posts to come… someday! I am pretty busy lately

C: Trick or Treat?

find something new: it teaches you to be humble about your programming wizardry. Today I have found two new mind-melting techiques which can cause serious brain damage:
Duff’s Device: speeding-up tight loops by unrolling and using a switch statement [...]

C language explanations
Regarding this little quiz, here I will write down proper explanations for the snippet of code which does array access using the “2[p]” syntax instead of the usual “p[2]” form. In order to properly understand which is going under the roof, I will try to explain things from the ground up, starting with some basic [...]
