Fundamentals of Programming (GCSE Computer Science AQA)

What is selection programming?

• A condition selects which code to repeat.

• A condition selects which lines of code to run.

• Any code that selects variable assignments.

• Selecting to run every single line of code.

While loops and for loops are examples of ...

• selection programming.

• sequential progtramming.

• iteration programming.

• boolean programming.

name <-- USERINPUT("Enter name: ")

pirateName <-- "Cap'n" + name

OUTPUT "Aye aye " + pirateName

• This is iteration programming.

• This is selection programming.

• This is Python programming.

• This is sequence programming.

A real/float data type is ...

• Any decimal or whole number, positive or negative.

• Any whole number, positive or negative.

• Any real word in the dictionary.

• Any True boolean statement.

The name of the data type that is either true or false:

• Integer

• Real

• Boolean

• String

Which data type can be described as a list of a different data type.

• Integer

• Character

• Boolean

• String

Select the valid structure for a single if statement:

• IF ELIF ELIF ELSE ELSE

• IF ELIF ELIF ELIF ELSE

• ELIF IF ELIF ELIF ELSE

• IF IF ELIF ELIF ELSE

a <-- 7

IF a <= 5 AND a >= 0 THEN

a <-- 5

ELIF a > 5 THEN

a <-- a

ELSE

a <-- 0

ENDIF

OUTPUT a

• Final output is 7.

• Final output is 0.

• Final output is 5.

• Syntax error, final output cannot be determined.

Where does the selection statement start?

a <-- 7

IF a <= 5 AND a >= 0 THEN

a <-- 5

ELIF a > 5 THEN

a <-- a

ELSE

a <-- 0

ENDIF

OUTPUT a

• line 1

• line 2

• line 4

• line 6

Which line uses variable assignment?

a <-- 7

IF a <= 5 AND a >= 0 THEN

a <-- 5

ELIF a > 5 THEN

a <-- a

ELSE

a <-- 0

ENDIF

OUTPUT a

• line 1

• line 2

• line 4

• line 6
