Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..
using System; public class functionexcercise { public static int Sum(int num1, int num2) { int total; total = num1 + num2; return total; } public static void Main() { Console.Write("Enter two numbers: "); int number1 = Convert.ToInt32(Console.ReadLine()); int number2 = Convert.ToInt32(Console.ReadLine()); Console.WriteLine("\nThe sum of two numbers is : {0} \n", Sum(number1, number2)); Console.ReadLine(); } }
