   output will be

   output will be-     a=98
   
   the value of --b =30-1=29
   
   
   the value of c++ =40
   
   
   the value of again b =29
   
   
   so the output will be 
   
   
   a=29+40+29=98
   
   
   a=98 (ANS.)

   They are both String functions used in Java.
   
   Equals() method just checks whether String 1 = String 2. It is used to check
   the equality of 2 strings. Its syntax is:
   
   
   boolean variable = String variable1.equals(String variable2);
   
   
   it returns only a boolean value: true or false.
   
   
   However,  CompareTo() function is used to not only check whether one string
   is the same as the other, but also to state which is greater, according to
   the ASCII values of the corresponding characters in the Strings.
   
   
   SYNTAX:
   
   
   int variable = String variable1.compareTo(String variable2);

   InputStreamReader (System.in));
           System.out.println ("Enter the value of n: ");
           int n = Integer.parseInt(stdin.readLine());
           int even =0, odd=0;
           for (int i = 1; i<=n; i++)
           {
               if (i%2==0)
               {
                   even = even+i;
