Algorithm and Flowchart Quiz

What is an algorithm?

• A flowchart

• A decision

• Step by step instructions used to solve a problem

• A flowchart or pseudocode

What are the three algorithm constructs?

• Loop, input/output, process

• Sequence, selection

• Input/output, decision, terminator

• Input, output, process

What is the difference between a flowchart and pseudocode?

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

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

• A flwochart and pseudocode are the same thing

• A flowchart is textual but pseudocode is diagrammatic

In a flowchart an input or output instruction is represented by

• A parallelogram

• A rectangle

• A rhombus

• A circle

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

• A rhombus

• A parallelogram

• A rectangle

• A circle

A flowchart needs to represent 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?

• Sequence

• Loop

• Decision

• All of the above

A flowchart needs to represent 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?

• Loop

• All of the above

• Sequence

• Decision

Programming languages give computers instructions

• True

• False

When you write an algorithm the order of the instructions is very important.

• True

• False

In a flowchart how are symbols connected?

• Symbols do not get connected together in a flowchart

• With solid lines to link events

• With lines and an arrow to show the direction of flow

• With dashed lines and numbers
