^ i like that link.

i don't think there's an equation without using summation. i tried to think about it for a minute, but gave up. I'm not really a math guy. :D

it's just LaTeX markup tags. any reference will describe the basics

and you don't need a "Big Number Library". you dont even need a long int. 10,000 is easily represented by a regular integer

the way to approach this problem is by summation:
...

the formula posted by siddhant is fundamentally flawed. it only appeared to work, because it just happened to be valid for n=2 through n=8. as 'n' increases past 8, the result becomes more and...

I say that you should avoid the use of old, non-standard libraries like "conio.h" unless you are explicitly instructed -- required -- to do so.

anyone can quickly learn to use any library...

it's not "jephthah approved". it's "industry acceptable".

i felt my post was quite constructive: I gave several links to a variety of modern and free standard-C compilers without prejudice....

whether it's currently practical or popular isnt the question. the question was whether C++ defines a byte as being exactly 8 bits. as several of us have learned, it does not. it can be 8 or...

i, too, believed the same thing Tux did.... thanks Narue for the detailed lesson. i learn a lot here.

now look, here's your chance, adatapost: don't screw it up. think before you post. and get rid of your...

cycle through each lettter in the alphabet, a through z, and check each letter if it repeats.

remember that ascii code character A is decimal 65 and Z is decimal 90. lowercase a is decimal 97...

i think that's a good idea.

use a non-numeric character (like 'b' or whatever) as the sentinel to stop taking input

and if you want to get fancy, you could use the '+', '-', '=' characters as...

okay. sorry. his implementation of the basic sentinel concept is just fine.

but a calculator that spontaneously shuts down when you try to add 9999... well, it just isn't going to sell really...

that's dumb.

what if he wants to add 9999 as one of his numbers

this is retarded.

you won't get a reading from the free electrons in the air. you'll get a reading from the noise of the instrumentation pathway, which is deterministic.

now, i'm glad you're...

or maybe you could sprinkle some magic fairy dust, and use some "sort of analog device" to aggregate the quantum velocities of the fairies at any given point according to Heisenfairy's Uncertainty...

there's your problem: nothing is truly random. some things are just less predictable than others.

the fact is, you're never goign to generate truly random numbers, even if something like that...

this assignment has never been given before!!!!11

I'm happy to hear you are so well-informed.

so now there's no reason for you to continue promoting MD5 as an algorithm that produces unique hash values, yes?



what a terribly fatal...

not true. MD5 is broken.

^ nice answer.

except one thing needs a bit stronger emphasis.

never, ever use "GOTO" this is not BASIC programming. You will be tarred and feathered.

why would you care if the numerator is zero? are we no longer allowed to add or muliply zero?

it seems i missed the memo ... again.

:(

this doesnt make any sense. what's any of this got to do with Windows API?

you've got an 8x8 matrix of single characters... what meaningful information can you have in such a thing?

you...

a char will hold a single character, which is just an 8-bit int.

what information are you trying to contain in any 'square'?

this doesnt seem very meaningful, to have one char value in any...

quintillion? thats not a large number.

now about seven years ago, i worked on a cryptographic accelerator with a 4,096-bit number... that was large

sweet.

my doctor just wants me to bend over and take a deep breath. :(

i should look into changing plans.

and neither do those $99.00 links :)



.

what, does everyone here have an ACM membership?

am i the only one who doesnt?

because i was interested in your links, so i went to check it out (the one about Hamilton Paths)

and well,...

too bad most people on here don't have membership to ACM.

this is a job for regular expressions.

try using the Regex++ library for C++

yeah ... i'm just not seeing where the "Urgency" is here

i thought someone was bleeding on the floor.

this thread made me laugh.
