1. String is a value type.
2. String literals can contain any character literal including escape sequences.
3. The equality operators are defined to compare the values of string objects as well as references.
4. Attempting to access a character that is outside the bounds of the string results in an IndexOutOfRangeException.
5. The contents of a string object can be changed after the object is created.

1. Single f = 9.8f; 
   String s;
   s = (String) (f);

2. Single f = 9.8f; 
   String s;
   s = Convert.ToString(f);

3. Single f = 9.8f; 
   String s;
   s = f.ToString();

4. Single f = 9.8f; 
   String s;
   s = Clnt(f);

5. Single f = 9.8f; 
   String s;
   s = CString(f);

String s1 = "ALL MEN ARE CREATED EQUAL";
String s2;
s2 = s1.Substring(12, 3); 
Console.WriteLine(s2);

String s1="Kicit";
Console.Write(s1.IndexOf('c') + " "); 
Console.Write(s1.Length);
