 {
     static void Main(string[] args)
     { 
         String c = "i love Csharp";
         bool a;
         a = c.StartsWith("I");
         Console.WriteLine(a);
         Console.ReadLine();
     }
 }

2. What will be the output of the following C# code?

class Program
{
    static void Main(string[] args)
    { 
        String s1 = "I love You";
        String s2 = s1;
        Console.WriteLine((s1 == s2) + " " + s1.Equals(s2));
        Console.ReadLine();
    }
}

 {

     { 
         String []chars = {"z", "x", "y", "z", "y"};
         for (int i = 0; i < chars.Length; ++i)
         for (int j = i + 1; j < chars.Length; ++j)
         if(chars[i].CompareTo(chars[j]) == 0)
         Console.WriteLine(chars[j]);
         Console.ReadLine();
     }
 }
