Question 4

Complex Conditions

Answer 4

AND – both conditions must be true e.g. gender = “M” AND age > 18
OR – either of the conditions must be true e.g. class = 1 OR class = 3
NOT – the condition should not be true e.g. NOT (gender = “M”)

Question 5

What is a Fixed Loop?

Answer 5

When a group of instructions is repeated a pre-determined number of times.
FOR counter 0 TO 5 DO
SEND “All work and no play makes Jack a dull boy” TO DISPLAY
End For

Question 6

What is a Conditional Loop?

Answer 6

Will keep repeating a group of instructions until a specific conditional is met.
GET password FROM (STRING) KEYBOARD
WHILE password != “letmein” DO
    SEND “In-correct” TO DISPLAY
    GET password FROM (STRING) KEYBOARD
END WHILE

Question 7

What are the three Predefined functions?

Answer 7

Round – rounds a value to a specific number of decimal places.
SET pi TO 3.141592
SET pi TO ROUND (pi, 2) → the new value of pi will be 3.14

Length – give the number of character present in a variable.
SET word TO “Mississippi”
SET numWord TO LENGTH (word) → the value of numWord would be 11

Random – generates a random number, between a lower and upper range.
SET bonusBall to RANDOM (1,59)

Question 8

What is the round predefined function?

Answer 8

Round – rounds a value to a specific number of decimal places.
SET pi TO 3.141592
SET pi TO ROUND (pi, 2) → the new value of pi will be 3.14

Question 9

What is the length predefined function?

Answer 9

give the number of character present in a variable.
SET word TO “Mississippi”
SET numWord TO LENGTH (word) → the value of numWord would be 11

Question 10

Answer 10

generates a random number, between a lower and upper range.

SET bonusBall to RANDOM (1,59)

Question 11

WHILE score < 1 or score > 100 DO
    SEND “In-Valid” TO DISPLAY
    GET score FROM (INTEGER) KEYBOARD
END WHILE

Question 12

A program must calculate the total cost of 5 items. Please write the code in pseudocode for this program.

Answer 12

SET total TO 0
FOR counter 0 TO 5
    GET itemPrice FROM (REAL) KEYBOARD
    SET total = total + itemPrice
END FOR

Question 13

A program is required to count all A grades. Please write the code in pseudocode for this program.

Answer 13

SET grade TO [A, B, C, A, A, B, A, C]
SET numA TO 0
FOR counter 0 TO 7
    IF grade[counter] == “A” THEN
         numA = numA + 1
END FOR
