In the above example, the initial value is 1. The final value is 100 and the incremental value
                  is 5. The next number is 105, which is outside the range, and therefore, the program comes

                  out of loop.

                  Program 4: To print all the even numbers upto the number entered by the user.

                  The  loop  continues to  execute  until the  condition is  achieved.  Let  us  see  how  this  was
                  achieved:

                  Step 1:  Initialise the variable a with the value 13.
                  Step 2:   Execute the for loop with initial value as 1 and final value as 11 and The loop

                            increments by 1 each time.

                  Step 3:  Store the multiplication answer in another variable b.

                  Step 4:  Print the value of b for each iteration.

                   The while Loop


                  A while loop is used when the number of iterations are not known to the user before running
                  the loop. As long as the condition given is True, the loop will continue to repeat.
