+* Objectives
+  At the end of this tutorial, you will be able to, 
+  - Define strings in differnt ways.
+  - Concatenate strings. 
+  - Print a string repeatedly. 
+  - Access individual elements of the string.
+  - Learn immutability of strings.
 * Question 1
   Obtain the string ~%% -------------------- %%~ (20 hyphens) without
   typing out all the twenty hyphens.

-    s = "%% " + "-"*20 + " %%"
-  #+end_src
 * Question 2
   Given a string, ~s~ which is ~Hello World~ , what is the output of::

 * Summary
-  In this tutorial we have learnt

+  In this tutorial, we have learnt,
+  - To define strings in differnt ways.
+  - To concatenate strings by performing addition.
+  - To repeat a string 'n' number of times by doing multiplication.
+  - To access individual elements of the string by using their subscripts.
+  - Use the concept of immutability of strings.
+
+* Evaluation
+  1. Write code to assign s, the string ``' is called the apostrophe``
+
+  2. Given strings s and t, ``s = "Hello"`` and ``t = "World"`` and an
+   integer r, ``r = 2``. What is the output of s * r + s * t?
+
+  3. How will you change s='hello' to s='Hello'.
+
+    - s[ 0 ]= H
+    - s[ 0 ]='H'
+    - strings are immutable,hence cannot be manipulated.
+* Solutions
+  1. s = "` is called the apostrophe" 
+
+  2. HelloHelloWorldWorld
+     
+  3. Strings are immutable,hence cannot be manipulated.
