Flowcharts and Pseudocode

What should be considered when designing an algorithm?

• If there is more than one way of solving the problem

• If the correct hardware is being used

• If the correct software is being used

What are the two main ways that algorithms can be designed?

• Images or videos

• In pseudocode or as a flowchart

• By hardware or software

What is pseudocode?

• A way of describing a set of instructions in text form

• A specific programming language that all computers use

• A diagrammatic representation of a set of instructions

What is a flowchart?

• A flowchart is a text-based way of designing an algorithm

• A flowchart is a specific programming language

• A flowchart is a diagram that represents a set of instructions

What is important to remember when designing an algorithm?

• whether to use a flowchart or pseudocode

• the instructions are in the correct order

• that it must be easy to read

What flowchart symbol does this represent?

• Input/Output
• Start/End
• Decision
• Process

What is this symbol?

• Decision
• Input/Output
• Start/End
• Process

What are the three types of control structure?

• Sequence, selection, repetition

• Input, output, process

• Input/output, decision, terminator

• Loop, input/output, process

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?

• Selection

• Repetition

• Sequence

• All of the above

To repeat a task number of times, we use

• input statement

• conditional statement

• loop statement

• output statement
