Solution:

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

namespace calculator
{
    class Program
    {
        static void Main(string[] args)
        {
            float a, b,c, result;
            Console.WriteLine("Add Sub Mult Div\n ");
            Console.WriteLine("Enter the a");
                a = float.Parse(Console.ReadLine());
            Console.WriteLine("Enter the b");
            b = float.Parse(Console.ReadLine());
            Console.WriteLine("1 for Add\n 2 for Sub\n 3 f0r Mult\n 4 for Div\n ");
            Console.WriteLine("Enter the c");
            c = float.Parse(Console.ReadLine());
           
            if (c==1)
            {
                result= a + b;
                Console.WriteLine(result);
            }
            if (c==2)
            {
                result = a - b;
                Console.WriteLine(result);
            }
            if (c==3)
            {
                result = a * b;
                Console.WriteLine(result);
            }
            if (c==4)
            {
                result = a / b;
                Console.WriteLine(result);

            }
            Console.ReadLine();

           

        }
    }
