                 Look at these binary codes of numbers 1-10.

                    Now answer the following in binary numbers:
                    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. The different conditional
              statements used in a program are:

              if-then-else

              The program executes the statements written after ‘if’ when the if condition is true. If the condition is
              false, the statements written after ‘else’ will be executed.
