                     2.   The statements used to repeat a set of instructions in a
                        program are called iterative statements or looping statements.                       .....................

                     3.   The WHILE statement is used to repeat a task for a fixed number of times.          .....................
                     4.  While loop is a replacement of the If…Then statement.                               .....................

                     6.  BASIC-256 provides two types of looping statements FOR...NEXT and IF-THEN.          .....................

                     3.  Consider the given program and answer the following questions.

                        sum = 0
                      FOR N = 1 TO 30 STEP 3

                      sum = sum + N
                      NEXT N

                      PRINT "sum = " + sum
                       a.  How many times the above loop will run?               ............................................................................

                       b.  What will be the output of the above program?         ............................................................................

                      IF (N = 1 ) THEN
                      PRINT "I had " + N + " slice of pizza."
                      ELSE
                      PRINT "I had " + N + " slices of pizza."
                      END IF
