Evaluate binomial coefficients

This programming task, is to calculate ANY binomial coefficient.

Evaluate binomial coefficients
You are encouraged to solve this task according to the task description, using any language you may know.

This formula is recommended: n!/k!(n-k)!

C++

<lang cpp>

double Factorial(double nValue)

  {
      double result = nValue;
      double result_next;
      double pc = nValue;
      do
      {
          result_next = result*(pc-1);
          result = result_next;
          pc--;
      }while(pc>2);
      nValue = result;
      return nValue;
  }

double EvaluateBinomialCoefficient(double nValue)

  {
      double result;

      result = (Factorial(m_nValue))/(Factorial(nValue)*Factorial((m_nValue - nValue)));
      nValue = result;
      return nValue;
  }
