Write C# Program to find the Largest among Three Variables using Nested if

I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..

using System;
 
namespace csharpprograms
{
    class Program
    {
        static void Main(string[] args)
        {
            int num1, num2, num3;
            Console.WriteLine("Enter three numbers: \n");
 
            num1 = Convert.ToInt32(Console.ReadLine());
            num2 = Convert.ToInt32(Console.ReadLine());
            num3 = Convert.ToInt32(Console.ReadLine());
 
            if (num1 >= num2)
            {
                if (num1 >= num3)
                    Console.WriteLine(num1+" is the largest number");
                else
                    Console.WriteLine(num3 + " is the largest number");
            }
 
            else if (num2 >= num3)
                Console.WriteLine(num2 + " is the largest number");
 
            else
                Console.WriteLine(num3 + " is the largest number");
 
            Console.ReadLine();
 
 
        }
    }
}

Result:

Enter three numbers: 

10

20

30

30 is the largest number
