Step 2:  Click on ‘Variables’, select ‘Make a variable’, write the name of the variable as ‘a’,
                            then click on ‘OK’. Variable ‘a’ will appear in ‘Make a Variable…’.


























                  Step 3:  Select the ‘Change a by 1’ block, click on the value a, and change the value to 10.

                  Step 4:   Drag and drop ‘change a by 10’ block to ‘on start’ block.














                      Well done, you have learned to create and initialize a variable!

                    State whether the following statements are true (T) or false (F).

                    a.    Variable is a name given to a storage area.


                    b.  A variable is declared but is not initialized ever has a null value.



                 DATA TYPES IN PROGRAMMING
                 Data type  identifies  the type  of  data which  the  declared  variable can  hold.  It  helps  the
                 computer to understand what operations need to be performed on the declared variables.

                 To declare the variable, you need to define:

                    name of the variable                               its type

                                                                                          Variables in Real Life   9
