You say that there is no chanse to resolve it so can you prove it mathematiclly?

That'll work! It satisfies the requirements of not using a list, array, etc. Big Grin | :-D

Can't you keep a running total and the number of inputs in two variables. Then you can calculate the average and of course half the number of variables is above the average. Or am I missing something?

missing something
calculating the average "on the run" is easy to do with a float and an integer.
but to tell how many of the inputs were upper than the average... no chance if you don't store the datas...

That outliers can skew things quite a bit. Given the set {1, 2, 5, 7, 10, 18}, the average is 7.1. Four numbers in the set are below this, and two numbers are above.

it's not possible; as soon as you receive a new number the average will be modified, and since you cannot keep an history of the values already read, there is no way of determining what numbers that you already read that are above or below the average.

(unproven, and unverified )
The problem with the average is that you can have a new value that will completly "unbalance" the computed average, for example you have a series of values in the [1, 10] range, the average will be between those 2 values, but if at some point you have a very large value, it will mess the result, and statistically the result will not be valid, unless you can filter out those bad values.

( but I expect someone to come with a brilliant mathematical answer that will awe us )

I'm guessing recursion is your friend here, assuming a magic computer that'll never stack overflow

Pseudo-C-ish-code

above_average = 0;

void main()
{
  doit(0,0)
  print( above_average " of your numbers were above average )
}

int doit( int sum, int count )
{
  print( "enter number, -1 to end" );
  int input
  get input from keyboard

  int average;
  if input == -1
  {
    average = sum/count
  }
  else
  {
    average = doit(sum+input, count+1)
    if( input > average )
    {
      above_average++
    }
  }
  return average 
}

Now remember, your lecturer is probably reading these forums....

(Technically, this is using a stack, just not the kind of stack most people would think of!)

Declaring variables and calling functions would violate the "no stack" requirement! Nice solution, BTW.

Hello guys,I'm Pardi Banjarnahor. I come from Indonesia.

If you don't mind, I want to ask you for help. Now, i want to create (make) a "client-server Program" with visual C++ 6.0.

That program should able act as a client or severt. either as a client/server, it should be possible to send data from client to server, and viceversa.

If you are one who used to programming visual C++ or can give me some advice or help, I'm so grateful if you would do that.

Thank You Very Much

Pardi

N.B: Please Help Me, I'm so very in need abput client-server application with visual c++.
you can directly cantact me through e-mail: pardibanjarnahor@yahoo.com

Thanks and GBU

What type of application do you want to create?

Pardi Banjarnahor wrote:

If it's a MFC based application...
You can use CSocket/CAsyncSocket clases to create a client/server application.
You can find a lot of articles on codeproject for doing the same.

Somethings seem HARD to do, until we know how to do them.

How do I pack to integer values in a double ?

How do I pack two integer values in a double ?
i.e

<br />
int x=1000;<br />
int y=2000;<br />
<br />
double z;<br />

now I want the first four bytes to be occupied by x and the next 4 by y in Z
How do I do that? any shift operators would help? please tell me how do I pack & unpack it?

toxcct3-Oct-06 3:49

what about using union ?

union U {
    double _d;
    int _i[2];
};

Thank you for your reply sir, But I do not want an union Frown | :(

The matter is,

You have a function like this. Imagine you cannot change it's params. It's built by someone and it's used in numerous instances.

<br />
void testDouble(double d)<br />
{<br />
cout<<d;<br />
}<br />

Now you say , testDouble(2143250); it prints 2143250. Now I want to send two integer values to this function for other reason. I have two numbres, 1000, 2000. these are ints so takes only 4 bytes.

<br />
double 00000000000000000000.....64<br />
now    0000000..32 | 0000.......32 is my idea.<br />
<br />

But how do I do that?

So that in the function, I can do like,

void testDouble(double d)
{
cout<<(HIGHER32)d;
cout<<(LOWER32)d;
}

get me now?

toxcct3-Oct-06 4:03

3-Oct-06 4:03

wait, you want to merge 2 ints into a double, or split a double into 2 ints ?

BTW be careful, sizeof(int) == 4 only on 32 bits plateforms !
