Principles of Computer Science

What is Computational Thinking?

• Thinking about how computers work things out

• the objective analysis and evaluation of an issue in order to form a judgement.

• Abstraction, Decomposition, Pattern recognition, Algorithm Design

• Nothing to do with Computer Science

Decomposition is:

• what happens in the compost heap

• To break things down into easier to handle chunks

• Getting rid of unnecessary information

• Creating a step-by-step guide to do something

Which of these are you familiar with?

• Variables

• Outputs

Which of these is not a variable type?

• String

• Bool

• Alphanumeric

• Integer

Have you coded in:

• C, C++, or C#

• Java

• Python

• I have no programming experience

what is the formal name in computing for looping?

• Iteration

• Selection

• Repetition

• For While Do

Selection uses which command?

• While

• Repeat Until

• IF

• x=x+1

Which paradigm is known for encapsulating the data structure with the functions

• Procedural

• Functional

• Object Oriented

• Event driven

X = 20;

Y = 5;

Y = X+Y

X++;

• X = 20, Y = 25

• X = 20, Y = 5

• X = 21, Y = 25

• X = 20, Y = 26
