power

how do you do powers with a for loop?

Just loop n times and multiply val by itself:

Code:

---

int power ( int val, int n )
{
  int ret = 1;

  for ( int i = 0; i < n; i++ )
    ret *= val;

  return ret;
}

-Prelude

There is a function called exp();. This is found in math.h. The syntax is
exp(number,power);

I know this isn't a for loop, but it is a differrent method.
