Hey.

Ok, I have a program in which the user enters a value and then I call a function which uses that value for a calculation.

Code:

int xpower(int x)
{
   int n = 3;
   int power = 1;
   int i = 0;

   while (i < n)
   {
      power = power * x;
      i = i + 1;
   }
   return power;
}

So the value the user enters is x and n is the power....so x^n.
The equation I must use...n HAS to start at 3. I want to use the function, return the value then increment n by 2, the problem I think I have is that everytime I use the function i basically reset n to 3....so is there any way I can get around this?

DUUUUUUUUUUUUUUUUUUUUUUHHHHHHHH, man I miss the sillyest things :x.

I've just seen it myself loool.

I took n out of the function, it didn't need to be there at all.
I initialised n in the main body and added another parameter in the function.

Thanks for looking anyway o_O
