In the second round, Harry and Jerry are both at the same
                                             level.








                  In the third round, Jerry is at a higher level. Thus, the
                  cycle goes on.

                  Repeating a set of steps is called a loop.



                      UNDERSTANDING PROGRAMS

                  A computer understands step-by-step instructions written only in a unique language,
                  called as program. The computer reads the program we write and follows as per
                  our instructions.
                  Let's write the steps to make a square.





                      Move 2 steps right.

                      Move 2 steps up.
                      Move 2 steps left.

                      Move 2 steps down.




                                                                                        Start

                  Similarly, we can write the steps to make a rectangle.



                      Move 2 steps right.

                      Move 1 step up.
                      Move 2 steps left.

                      Move 1 step down.
                                                                                        Start
