申論 1以下是完整的C#程式碼，請回答以下各小題執行的結果為何？（每小題10 分，共20 分）㈠internal class Program {static void Main(string[] args) {float p = 5.5f;int r = calc_square(p);Console.WriteLine(String.Format("Result:{0}", r));}static int calc_square (float param) {int result = (int)(param * param);return result;}}㈡static void Main(string[] args) {float rate = 2.5f;float amount = 10f;computing(rate, ref amount);Console.WriteLine(String.Format("Rate: {0}, Amount: {1}", rate, amount));}static void computing(float rate, ref float amt) {rate *= 10;amt *= rate;}
