Ode to C

May your signals all trap 
    May your references be bounded 
All memory aligned 
    Floats to ints rounded 

Remember ...

Non-zero is true
  ++ adds one
Arrays start with zero
  and, NULL is for none

For octal, use zero
  0x means hex
= will set
  == means test

use -> for a pointer
  a dot if its not
? : is confusing
  use them a lot

a.out is your program 
 there's no U in foobar 
and, char (*(*x())[])() is 
 a function returning a pointer 
 to an array of pointers to 
 functions returning char

    Nice blog you have! I guess you have downloaded this template from blogger-templates? I also used this template for my earlier blog but it was unfortunately deleted when I created a new one. You can't download it anymore and I wonder if you still have the html-code? If you have, do you think you can e-mail it to me, please? I would appreciate it a lot! Keep up the good work!

    Have a nice evening!

    Ever heard of mathematician who refused to learn C saying that it is inconsistent when he encountered the following statement?

    X = X + 1;

    Jokes apart.
    ++adds one, before or after?

    Also few from my side (top of the mind)
    1.void * means something
    2.To have { in the same line or the next line, that's the question
    3.You can write/read from anonymous unions
    4.Ignore the evils macro at you own peril!

    Emelie, I will try to get the code for you.
    Ankur, thanks for your comments!

    x++ does it after
    ++x does it before

    1.void* x declares a pointer x of type void. It is a universal pointer that can have any pointer assigned to it. Generally used for allocating memory.

    2.Style says { should be in the same line

    3. not sure about this one

    4. agreed!
