What is an algorithm?

• A) A flowchart

• Step by step instructions used to solve a problem

• A flowchart or pseudocode

• A decision

What are the three algorithm constructs?

• Sequence, selection, repetition

• Input, output, process

• Input/output, decision, terminator

• Loop, input/output, process

What is the difference between a flowchart and pseudocode?

• A flowchart is diagramatic while pseudocode is written in a programming language (eg. Pascal or C)

• A flowchart is textual but pseudocode is diagarmmatic

• A flwochart is a diagrammatic description of an algorithm whilst pseudocode is a textual description of an algorithm

• A flwochart and pseudocode are the same thing

In a flowchart an input or output insruction is represented by

• A rectangle

• A circle

In a flowchart a calculation (process) is represented by

• A rectangle

• A rhombus

• A parallelogram

• A circle

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 its' 50 or over award 'Pass', else it awards 'Fail'. This is an example of which of the algorithm constructs?

• Sequence

• Decision

• Loop

• All of the above

A flowchart needs to represent the a situation where the user is asked to enter his age, the age is read into the system and the system outputs a 'Thank You' message. This is an example of which of the algorithm constructs?
