Flowcharts Flashcards
What is a diagram made up of?
symbols like diamonds or squares (didn’t know squares were so symbolic bro)
What does the diagram represent and how are steps shown?
It represents a sequence of events in the correct order from start to end in a flow from left to right or top to bottom (catch this flow does arm wave)
oval
begin/end (beninging)
parallelogram
input/output (going in tonight)
rectangle
process/calculations (processing this ict info)
rhombus
decision (sumn i cant make)
arrow
flow line and direction of progress (want my flow again bro)
flow charts start and end with what symbol and how many arrows leave said symbol
the oval (start and end) symbol and only 1 arrow leaves it (symbolic dude yah)
Every flowchart stage should be listed out in a _______ order and it should be _____, _____ and ____ __ ______
logical; clear; neat; easy to follow (opposite of me)
How many lines should come out from a process symbol?
one (uno)
How many flow lines may enter and leave a decision symbol?
one may enter but two or three may leave depending (uno out)
advantages of using flow charts
● Good way to communicate the details of a task or
process to others
● Excellent way of documenting each stage in the
process
● Help people analyze problems or bottlenecks in the
process
● When a new system is being developed, flowcharts
can act as a guide or blueprint for the programmer.
disadvantages of flow charts
● Some processes or tasks are so complex that it
becomes difficult to represent them clearly in a
flowchart
● If an alteration needs to be made to the system, the
flowchart might need to be redrawn. If it was created by
hand, this could take a lot of work.
● People need to understand what a flowchart is for and
what the different symbols mean. It can look quite
daunting until you are familiar with the symbols.
conditional statement explanation fully
A conditional statement is responsible for modifying the SEQUENCE of a flowchart.
A conditional statement is always used with a condition. The condition is evaluated first before executing the different outcomes
Conditions can either be TRUE or FALSE
decision making in flow charts
Decisions are made by evaluating a conditional statement or question
Conditional can have ONLY TWO outcomes. These are either TRUE or FALSE.
The condition is phrased like a question with a ‘Yes’ or ‘No’ answer and placed in the decision box
There are ONLY TWO arrows LEAVING a decision box
These arrows must be labelled ‘Yes’ or ‘No’
