BTW - I am not asking for source code and I am not asking anyone to do

my homework as I do want to learn .. I just need a hint or two to get

moving and I need to know if what I have written so far is leading me

in the right direction ~

Ok - The problem is to find out how many people need to be in a room

for a 95% chance that someone in that room will match my birthday

I wrote a program that will calculate that percentage for any 2

bithdays to match, but that is not the same thing

Here is what I have so far:

#include "stdafx.h"

#include <time.h>

#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])

{

int sample[1000];

int i=1,j=1;

int a =0;

srand( (unsigned)time( NULL ) );

while (a != 325)

{ sample

*=rand()%365+1;*

//cout<<" "<<sample

//cout<<" "<<sample

*;*

a = samplea = sample

*;*

i++;

if (a==325) cout<<"\n\n\n Match "<<a<<" at "<<i<<"\n";

}

return 0;

This puts random numbers from 1-365 in an array - reads the array and

tries to detect an exact match

The problem is that the match is so random - how do I come up with a

95% chance? Is there any exact answer ?

As I said - just need some hints to move along..

Any replies will be appreciated,

Thanks,
