What will be output

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace TestFunction
{
    class Program
    {
        public static int ShowDetails(var a, dynamic b)
        {
            return (a + b);
        }
        static void Main(string[] args)
        {
            ShowDetails("Ashish", 100);
        }
    }
}

Note:- It will gives compile time error because we can not pass var as a parameter.
