Declaring Explicitly Typed VariablesDeclaring Explicitly Typed Variables

  1. Declare a variable called bigValue of type unsigned long. Initiate it with a value of 123456789.
  2. Declare a variable called smallValue of type integer. Initiate it with a value of 1234.

1. The keyword for unsigned long data type is ulong. 

using System;

namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Replace ___ with necessary data type
