The sprite will ask you to type your favourite fruit. When you press the Enter key, the name of
              the fruit appears in the speech bubble of the penguin. The name of the fruit then appears in
              the answer as well as in the variable name on the stage.





















              CONDITIONAL BLOCKS


              Many times, you have to do a task which is dependent on some condition. For example, you

              have to make mango shake. There are two conditions:

                a.   Go to the refrigerator and check if there are mangoes. If mangoes are there, then you will
                    make mango shake.
                b.   If mangoes are not there, you will make cold coffee.

                Here the condition is the availability of mango.

                We can also write this in two ways:

                 1. if                                               2.  if
                        mango is available                                       mango is available
                   then                                                   then

                        make the mango shake                                     make the mango shake
                                                                          else
                                                                                 make cold coffee


                 In such situations, we use conditional blocks. Scratch has two conditional blocks. They are:

                  If,then block: In this block if the condition is true, the blocks inside conditional block will

                 run. If the condition is false, the blocks inside conditional block will not run. Only the blocks
                 outside the conditional block will run.

                  If,then,..else block: In this block if the condition is true, the blocks inside then condition
                 will run. If the condition is false, the blocks inside else condition will run.

              You can also use the forever and repeat blocks with these blocks.
