                       Look at these binary codes of numbers 1–10.

                                   Number           Binary                   Number           Binary

                                       1             0001                        6             0110

                                       2             0010                        7             0111
                                       3             0011                        8             1000

                                       4             0100                        9             1001

                                       5             0101                       10             1010

                       Now answer the following in binary digits:

                       1.  Write all the prime numbers between 1 and 10.


                       2.  Write all the even numbers between 1 and 10.


                       3.  Write the sum of 5 and 4.



                       4.  Write all the numbers divisible by 3 between 1 and 10.





                  Conditions in a Program


                  While writing a program, we need to make certain decisions based on the logic of the program.
                  Such situations are called conditions. Conditional statements are used in a program to instruct the
                  computer to make a decision. The result of a condition will always be either True or False
                  IF-THEN-ELSE
                                                                                       Start
                  The program executes the statements
                  written  inside  the  IF  block when  the
                  condition  is True.  If the condition  is
                  False,  the  statements  written  inside                         IF (Condition)
                  the else block will be executed. A block        True             to be checked            False
                  refers  to  a  section  of  code  that  is   Statements inside IF             Statements inside ELSE
                  grouped together.                            block will execute                  block will execute



                                                                                       Stop
