Computernal Thinking Flashcards
Decomposition
Breaking down a problem into small more manageable ones
Abstraction
Sorting the information in to relevant information and irrelevant information and getting rid of the irrelevant information
Flowcharts -decision
Ask a question with either a yes/no true/false answer⬇️
🔶
⬇️
Flowcharts-direction of flow
Arrows are used to show the direction of flow within the algorithm
Flowcharts-start / end
Begin and finish your algorithm with this symbol
Flowcharts-tasks
Do something
Flowcharts - inputs / outputs
Used when you either want to input information into your algorithm or output information into your algorithm
Flowcharts-variables
Variables are used to store information and can be called back up later in the algorithm
Output a string of words
OUTPUT
Output both string and integers
OUTPUT
Output both string and variable
Score
Assign string to a variable
Player_name
Assign integer to a variable
Player score
Assign user input to a variable
Player_name
Assign string to an array
Names
Assign integers to an array
Scores
=
Equal to
>
Greater than
Less than
≠
Not equal to
> =
Greater than or equal to
<=
Less than or equal to
AND
All operators comparison must be true for a TRUE outcome
OR
Either operators comparison needs to be true for an TRUE outcome
NOT
The result will be the opposite
IF statement
IF[enter comparison]THEN
Enter task to preform
ELSE
Enter alternative task
END IFDN
Integer division-identifies how many times a number can be divided by a whole number
MOD
Modules division-Used to find the remainder after division
Pattern recognition
Pattern recognition is were they break down photos and voices into small data like colours and shapes and help find the same or simultar data somewhere else
