hmm, not gloating at all arrrrrrrrre we?! lol :P

 

i still got a case of the algebra squirts, mrboo :lol:

hahaha! well, the algebra stuff was rather trippy!

 

not gloating, not at all :rolleyes: The post did say something about fastest though :) So I know I am winning in that respect so far atleast. Not sure about comments / smartest code / blah though...

my algebra made sense and the equation worked!!

 

just that 32bit is too rubbish to handle it :lol:

and even 64 bit :rolleyes: big numbers....

After reading markie's post, I was inspired to see if I could slim mine down. So I made this:

#include <iostream>


int main()
{

  return 0;
  
}

Which compiles to 463kb with Dev. Meanwhile, markie's whole program compiled (again with the same Dev program) is a mere 18kb.

 

If I compile this:

//#include <iostream>


int main()
{

  return 0;
  
}

it's 15kb. I think iostream is a little bulky :P

 

So basically, I'm thinking C is going to win this battle every time. However, I would like to do some speed comparisons with my new code-in-progress, just for fun. Markie, could you elaborate a little on how you did your comparisons. Is this something you ran at the command line, or something you built into the codes?

im too complex for computers :(

:lol: demand 128 bit for personal computers...

 

BTW, Verran... you do know that ASCII 33 isn't actually 'a', right? Capital 'A' is 65 and small 'a' is 97... I did mine from 33 up till 126 too so the performance things would be meaningful.

Ah, that's probably the cause for the slowness as well then I expect...?

 

I did the speed tests, well, first

 

#include <windows.h>

 

Then 3 variables:

 

LARGE_INTEGER start, end, tps;

 

After the input for the number of characters:

 

QueryPerformanceCounter(&start);

 

Before system("pause");

 

QueryPerformanceCounter(&end);
QueryPerformanceFrequency(&tps);

printf("%d ticks per second\n", tps.QuadPart);
printf("done in %d ticks\n", (end.QuadPart - start.QuadPart));

Well, I've been trying a bunch of non-dynamic and non-recursive solutions, and they're really not that much faster. I guess the dynamic memory allocation couldn't slow it down that much, and the recursive calls really aren't much different from a for loop in principle. Maybe C is just a lot faster than C++ in this case. I do not admit defeat, but my language does :P

 

As far as the integer/ASCII values, yeah I know them all. I use this:

ASCIICodes.gif

to cheat! :) I've had a couple different versions. The first one was just a-z, and the other was !-~ or something like that, that's probably where the confusion was.

 

Thanks for the windows tick counter thing too. I got it working very easily, and I'm sure it will come in handy some time in the future.

 

###EDIT

Wow, that image looks like crap when linked to the boards. In a normal image viewer, it's just black on white and very easy to read. Fear not, if you download it, it'll look fine :P

Yeah it's probably just... the stream blah stuff making it slow. I will have to try your recursive thing in C and see if that's any quicker than my nasty iterative one... cause they should be very close in terms of speed... :blush:

 

I remember doing a comparison of something in Java using recursion and iteration before and the iterative version was ever so slightly faster, the difference being constant.

I am beginning to believe that I never stood a snowballs chance in hell from the start

Bah, it's not about competition, it's about a challenge. I thought I was "winning" til markie showed his little head, but who cares? I loved markie's post because it made me go back through my own code and work on it more. I just enjoy having -something- to code. Now that I'm outta school I don't get challenged with coding projects anymore, and I miss using that part of my brain. I can't wait til I find something else to work on :)
