Flowchart and Algorithm

What is an algorithm?

• A picture of a process

• A step-by-step set of instructions

• A programming language

• A type of flowchart

What does a flowchart represent?

• A data table

• A step-by-step plan to solve a problem

• A storybook

• A website layout

Which shape in a flowchart represents a decision?

• Oval

• Rectangle

• Diamond

• Circle

Why do we use flowcharts in programming?

• To write long code

• To create games

• To plan and visualize the steps of an algorithm

• To delete instructions

What will happen if you forget a decision point in your flowchart?

• The flowchart will still run smoothly

• It may cause the program to crash or act incorrectly

• The program will run faster

• It will display an error message automatically

What does a rectangle in a flowchart usually represent?

• Start or End

• Input or Output

• A comment

• A process or instruction

You are asked to make a cup of tea. Which step is NOT part of the algorithm?

• Boil water

• Add sugar

• Paint the kettle

• Put tea bag in cup

What flowchart symbol would you use to ask, “Is the water boiling?”

• Rectangle

• Diamond

• Oval

• Parallelogram

A flowchart has two decision symbols in a row. What does that tell you about the algorithm?

• It will always repeat

• It contains nested or multiple choices

• It only accepts input

• It has no process

Given the flowchart below (image or description), what is the output if the number is 3?
