Sorry dude, I didn't check earlier but just in case you still need it,
I have posted it below. You were missing two braces -- that was all.
// Program asks user to enter three integers
// Program displays a message indicating whether the numbers
// are in sequential order
// in reverse order
// or in neither order
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
public class DebugThree2
{
public static void Main(string[] args)
{
int num1, num2, num3;
string snum1, snum2, snum3;
Console.WriteLine("Enter first number ");
num1 = Console.ReadLine();
snum1 = Convert.ToInt32(snum1);
Console.WriteLine("Enter second number ");
snum2 = Console.ReadLine();
num2 = Convert.ToInt32(snum2);
Console.WriteLine("Enter third number ");
snum3 = Console.ReadLine();
num3 = Convert.ToInt32(snum3);
if(num1 <= num2 || num2 <= num3)
Console.WriteLine("Numbers are in sequential order");
else if(num1 >= num2)
{
Console.WriteLine("Numbers are in reverse order");
}
else
{
Console.WriteLine("Numbers are in neither sequential nor reverse order");
}
}
}
