2nd Tutorial of Metode Perancangan Program

True / False

  1. Array is a data structure that is made up of a number of variables all of which have the same data type
  2. Ease of understanding is one of the benefit of using the modular design
  3. Efficiency of maintenance means each module should be depend on other module
  4. Diagram that represents modules graphically is called organization chart
  5. One of the most common modules is an initial processing module

Complete the following pseudocode

  1. Program_1

____ smallest_element to array(1)

____ largest_element to array (1)

Do ________ = 2 to number_of_elements

                IF array (index) ____ smallest_element THEN

                                Smallest _ element = array(index)

                ELSE

                                ___ array(index) > largest_element THEN

                                                Largest_element = array(index)

                                ENDIF

                ENDIF

______

Print the range as smallest_element followed by largest_element

                _______

  1. Program_2

Set ________________ to false

Set low_element to 1

Set ____________________ to max_num_elements

DOWHILE (NOT element_found) _____  (low_element <= high_element)

                Index = (low_element + high_element) /2

                IF input_value = array (index) THEN

                                Set ________________ to true

                ELSE

                                IF element_found THEN

                                                Print array(index)

                                ELSE

                                                Print ‘value not found’, input_value

                                ENDIF

                END

  1. Program_3

Set max_num to 24

Set ____________ to zero

Read input file

DOWHILE (input values exist) AND (row_index< 6)

                row_index = row_index + 1

                DO column_index = 1 to 4

                                Freight_charges (row_index, ____________ ) = input value

                                ___________ input file

                ENDDO

IF (input values exist) AND row_index = 6 THEN

                Print ‘array size too small’

ENDIF

                END
