Question

Please code C#

1. Write a method with an int return type that has two int parameters. The method returns the larger parameter as an int. If neither is larger, the program returns -1.
   1. Call this method three times, once with the first argument larger, once with the second argument larger, and once with both arguments equal

Answer 1

using System;
public class main
{
    public static int Greater(int num1, int num2)
    {
        if(num1>num2)
        return num1;
        else if(num1<num2)
        return num2;
        else
        return -1;
    }
     
    public static void Main()
    {
    for(int i=0;i<3;i++)
    {
          Console.Write("Enter a number: ");
      int n1= Convert.ToInt32(Console.ReadLine());
      Console.Write("Enter another number: ");
      int n2= Convert.ToInt32(Console.ReadLine());
      if(Greater(n1,n2)!=-1)
      Console.WriteLine("The Greater of two numbers is : {0} \n", Greater(n1,n2) );
      else
      Console.WriteLine("The two number are same : {0}",Greater(n1,n2));
    }
    }
}    

Here is the program that will asks the user to enter two number for three times by using a for loop and every time will print whether num1 is greater or num2 is greater.If both are same then it prints -1 as output.
