Answer 1

Explanation:-

here, Enum is a primitive data type  which is user-defined.

using System;

namespace EnumApplication {
class EnumProgram {

//user defined data type
enum Days { Sun, Mon, tue, Wed, thu, Fri, Sat };

static void Main(string[] args) {
//it will give the week start that is monday position which is 1
int WeekdayStart = (int)Days.Mon;

//it will give the week end that is friday position which is 5
int WeekdayEnd = (int)Days.Fri;

Console.WriteLine("Monday: {0}", WeekdayStart); //it will print the value
Console.WriteLine("Friday: {0}", WeekdayEnd);
Console.ReadKey();
}
}
}
