Computational thinking, algorithms and programming

Which programming construct allows an algorithm to repeat instructions?

• Selection

• Assignment

• Iteration

• IF

A flowchart needs to represent the a situation where for each mark a student is award 'Pass' or 'Fail'...the system will consider the mark and if it's 50 or over award 'Pass', else it awards 'Fail'. This is an example of which of the algorithm constructs?

• Decision

• Loop

• Sequence

• All of the above

What are the three algorithm constructs?

• Sequence, selection, iteration

• Input, output, process

• Input/output, decision, terminator

• Loop, input/output, process

In a flowchart a calculation (process) is represented by:

• A rectangle

• A rhombus

• A parallelogram

• A circle

What does a parallelogram represent?

• Input/Output

• Decision

• Process

• Start/Stop

Define the term decomposition within computational thinking.

• The breaking down of a program until it no longer exists

• The creation of music that can be played on a computer

• The breaking down of a problem into smaller problems

• The breaking down of waste to make compost

Ignoring any information about a problem that isn't important is called...

• Decomposition

• Abstraction

What does an arrow represent in a flow chart

• Decision making

• Data Flow

• Start

• Stop

Define the term computational thinking.

• Using a computer

• Developing an algorithm to solve a problem

• Making a computer use artificial intelligence

• Google is computational thinking

Identify the correct definition for ‘algorithm’.

• A problem

• The steps that are taken to solve a problem

• A solution to a problem

• The words to enter when typing
