SUBROUTINES Pseudocode

In CIE Pseudocode we should always.. (pick one or more answers)

• Write command words in capitals

• Use DEFINE for every variable used

• Include comments

• Ensure that all subroutines are shown at the end of the program

What is the purpose of the back arrow ← in pseudocode?

• It means replace the variable with the new variable

• It means use the previous value of the variable

• It means assign to the variable

• It means check that the variable value is valid

In Pseudocode how can we create a subroutine procedure called drawSquare that will take a size input as a parameter?

• SUBROUTINE drawSquare(size: REAL):

• SUBROUTINE drawSquare():

  INPUT size (REAL)

• PROCEDURE drawSquare():

  INPUT size (REAL)

• PROCEDURE drawSquare(size:REAL):

Which are true about DEFINE statements in pseudocode?

• They give the data type of the variable

• They can occur anywhere in the program, provided it is before the variable is used

• They have the same purpose as def statements in Python

• Any variables used in the program or subroutine must be first shown with a DEFINE statement

Which of these statements are true?

• Subroutines can use variables that are not used in the rest of the progtram

• Subroutines can only use variables that are defined at the start of the program

• Suboutines in pseudocode may use parameters

• Subroutines may return a value

A function subroutine in pseudocode can be written as

• FUNCTION CountChar():

• SUBROUTINE CountChar():

• FUNCTION CountChar:

• SUBROUTINE CountChar:

Functions and Procedures are the same

• Yes

• No, procedures cannot use parameters

• No, procedures cannot use a RETURN statement

• No, functions cannot use parameters

When we run a subroutine in the main program it is called

• Assigning

• Calling

• Naming

• Iterating

In psuedocode, Which of these is the correct way to call a procedure called drawSqare(length), where the length is 3 ?

• CALL drawSquare(3):

• drawSquare(3):

• PROCEDURE drawSquare(3):

• SUBROUTINE drawSquare(3):

What is a parameter?

• The values that a function that calculates

• The name of a variable that can be used to give an input to a subroutine

• The value of a variable that can be used to givw an input to a subroutine

• The values that a function that calculates
