using System.Text;
namespace Test
{
class Program
{
static void Main(string[] args)
{
//variable declaration
long num = 12345;
//printing value
Console.WriteLine("num: " + num);
//printing type of variable
Console.WriteLine("Type of num: " + num.GetType());
//printing size
Console.WriteLine("Size of a long variable: " + sizeof(long));
//printing minimum & maximum value of long
Console.WriteLine("Min value of long: " + long.MinValue);
Console.WriteLine("Max value of long: " + long.MaxValue);
//hit ENTER to exit
Console.ReadLine();
}
}
}
