1000!
-
Plz help me to solve the below excise: Write a program to calculate 1000! in C# language I tried so hard and got so far
int i,f; f=1; string factorial=""; for (i=1; i<=1000;i++) { f= f*i; factorial = f.ToString(); //additional /*if(i==33) { break; } */ } this.label1.Text = factorial; but u can get factorial until 33 otherwise 1000! gives u result 0 (zero) _____________________ Proud to be Albanian _____________________

Professor? If this is an example of an assignment at your university, you may want to put a "stop" on that tuition cheque... Share and enjoy. Sean

Congratulations!! You just did his homework for him!! And WOW, he didn't learn a damn thing!! :laugh: RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

You need to use Stirling's formula, which asymptotically goes as n^n e^(-n). I'd prob take the log of this as a first calculation, or do something to avoid the n^n.

Yes but... this is an approximation (admittedly with an error approaching 1/n^2 for n=1000) and won't be good enough if the exact value is required. ...Steve 1. quod erat demonstrandum 2. "Give a man a fish and you've fed him for a day. Teach him how to fish and you've fed him for life." I read that somewhere once :-) (Translation: I'll show you the way, but not write the code for you.)

The problem is that you've defined

That's virtually an absurd comment. The guy didn't give a type, so I might guess a double (or long would be better). Moreover, the leading coefficietly are easily googlable. If he wants all the digits down to the decimal point then that's a completely different problem. ;P

The answer to 1000! is a whole number. So my comment still stands. Stirling's formula approximates the actual value (albeit a very good approximation) - there is some error involved.

Yep I agree, however since he has not given us any more information on the assignment question, this discussion is academic. :) ...Steve 1. quod erat demonstrandum 2.

Acording to the answer generated from Maple 10, I don't think a small litle program is going to solve this...
