Pseudocode & flowchart

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 the symbol for a decision in a flowchart?

• A parallelogram

• A diamond

• A circle

How are symbols connected together in a flowchart?

• Symbols do not get connected together in a flowchart

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

• By numbers

Which symbol is used for a connector in a flowchart?

• A parallelogram

• A diamond

• A circle

What is an Algorithm?

• A flowchart
• Step by step instruction used to solve a problem
• A decision
• A Pseudocode

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

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

• True

• False

To repeat a task number of times, we use

• input statement

• conditional statement

• loop statement

• output statement
