Question

I now that this question it has been mada many times but,
I need a function to calculate the sum of odd numbers in a given stack S

I have try something like this, but i now that it is not correct.

private static int Sum(int n, x)
{            

    if (n % 2 == 0) && (x % 2 == 0)
       return n + x;
}

Answer 1

just an example, you could pass your stack variable as an argument to the GetSum() function.

private static int GetSum()
        {
              Stack<int> stack = new Stack<int>();

            stack.Push(2);
            stack.Push(5);
            stack.Push(7);
            stack.Push(4);
            stack.Push(1);

            int sum = 0;

            foreach (int number in stack)
            {
                if (number % 2 != 0)
                {
                    sum += number;
                }
            }

        return sum;
    }
