Year 9 Computer Science Programming Test

In programming terms what is a sequence?

• A piece of code that is not used

• A special programming language

• A series of instructions carried out one after another in order

• A piece of hardware that the program is stored on

Why do we use high level programming languages like Python rather than directly typing in 0s and 1s?

• Because it allows us to give the computer instructions in a clear and unambiguous way

• Because it's slower than typing in 0s and 1s

• Because it's cheaper

• Because it gives us something to learn in out Computer Science lessons

What does the print instruction do in Python?

• Allows the user to enter their name

• Turns on our printer

• Makes some text appear on screen

• Loads the Windows Calculator

What is a variable?

• A piece of data that can be changed

• An instruction to the computer

• A number which remains the same

• A special instruction which is hidden from the programmer

When you type something incorrectly or miss out a character in your program what kind of error will you get

• Checksum error

• Hashing error

• 404 error

• Syntax error

What does an if..else statement do?

• Chooses which part of the code to run depending on a test

• Causes the computer to crash

• Makes the program repeat itself

• Allows the user to enter some data

What does iteration mean?

• Code which includes sound

• Code which never runs

• Code which is very quick to run

• Code which repeats multiple times

Splitting a big programming project into functions is useful because...

• It makes it easier to test the project

• Different people can work on different parts of the project at the same time

• It makes it easier to reuse parts of the code in other projects

• All of the above

Which symbol is used to create a comment in Python code

• @

• +

• ~

• #

Why do we test our programming code

• To show how good it is

• To find and remove any errors

• Because if we make a mistake our program will delete itself

• To add extra functions to our program
