* <loop body>
*
* where initialization usually declares a loop variable, condition is a
* boolean expression such that if the condition is true, loop body will be
* executed and after each iteration of loop body, expression is executed which
* usually increase or decrease loop variable.
*
* Initialization is executed only once.

* Loop body may contains more than one statement. In that case they should

Output would be

Index is : 1
Index is : 2
