Answer
int num1;
int num2;
Console.WriteLine("Enter a number: ");
num1 = int.Parse(Console.ReadLine());
Console.WriteLine("Enter another number: ");
num2 = int.Parse(Console.ReadLine());
if (num1 > num2)

Console.WriteLine("num1 is bigger.");
}
else if (num1 < num2)
{
Console.WriteLine("num2 is bigger.");
}
