Computational Thinking 3-Other algorithims

Question 1

Define

Algorithim

Answer 1

An algorithm is a plan, a set of step-by-step instructions to resolve a problem.

Question 2

How it works

Algorithim

Answer 2

Each instruction is identified and the order in which they should be carried out is planned.

Question 3

Define

Pseudocode

Answer 3

This is a method of writing up a set of instructions for a computer program using plain English.

This is a good way of planning a program before coding.
Pseudocode is not a programming language, it is a simple way of describing a set of instructions that does not have to use specific syntax.

Question 4

Define

Flowchart

Answer 4

A diagram that shows a process, made up of boxes representing steps, decision, inputs and outputs.

Flowcharts normally use standard symbols to represent the different instructions.

Question 5

What do these shapes correlate to in flowcharts

1. Oval
2. Rectangle
3. Arrow
4. Diamond
5. Parallelogram

Answer 5

1. (Terminal symbol)
2. (Process symbol)
3. (Arrow Symbol)
4. (Decision symbol)
5. (Input/Output symbol)
