How many basic data types are there?

• 3

• 4

• as many as you want

• data types?

Which is the odd one out?

• IF

• WHILE

• FOR

• DO...UNTILL

You want to show some code if the age is over 18, which is the correct command? (c#)

• IF (age < 18)

This is an array of 6 elements, called scores, which is the correct reference to access the element with -16 in it.

• scores[-16]

• scores[3]

• scores[4]

• scores(5)

You need an variable to act as a counter, what would be the best data type to use?

• Real/Float

• Integer

• String

• Bool

You are looking for a specific card in a deck of cards, which of the standard algorithms will you use?

• Quick search

• Binary search

• Bubble search

• Linear search

i++; is the same as writing:

• i = i +1;

• i = i * i;

• i = i - 1;

• GOTOWHILE;

What sort of datatype would you use to store someones name?

• String

• Int

• float

• bool

You have been given a problem to write the code for, what do you do?

• Use computational thinking to abstract the relevant information, decompose the problem, look for patterns and then design the algorithm.

• Go wibble wibble wibble, this is too hard, someone do it for me!!

• Have a quick read of the problem, and then code bash a solution out.

• look blankly at the teacher, blink a few times, and then turn back to your friend and continue the conversation.

What do you think this bit of Python code does?

• Ah-Ha! Its a sort algorithm

• I'm not fooled by your tricks, its a search algorithm

• I know its a security protocol program

• Netcode!
