Flowgorithm Working Process


Tutorial - 1 of 8

Step1

Using this short tutorial, you are going to create a very simple program called Hello World. It is a traditional 
beginner's program that displays "Hello, world!" on the screen.When you start a new flowchart, you will see
two rounded rectangles called "terminals". These symbols represent the beginning and end of your program.
Many flowcharts display the text "start" in the top terminal. Flowgorithm, however, uses the text "Main".
 Most programming languages start with "Main" and Flowgorithm attempts to be consistent.

Step2
Everything in a flowchart is represented by a shape. You will add your own shapes between the Main and End
terminals. To add a shape, move your mouse pointer over a line. If you can add a shape, the line will turn 
orange. Now, either double-click or right-click to add a shape.

Step3

A pop-up menu will appear that shows all the shapes you can add.
In flowcharts, each action your computer can perform is represented by a different shape. For example, input
and output shapes are represented with parallelograms (slanted rectangles).  You can also paste from the 
clipboard using this menu. In the picture, it is grayed-out, so there isn't anything to paste yet.


Step4

The Hello World program needs an output shape. It will allow the program to display information on the 
scree. Move the mouse over the green parallelogram  with the text "Output". It will highlight in blue.
Click on the shape. It will be added to your flowchart.













Step5

Now your flowchart contains an output shape.
Currently, it is displayed in gray. In Flowgorithm, any shape that is gray is "incomplete". This means that the 
shape needs some information before it can work. You need to tell Flowgorithm what you want it to output. \
This can be anything from the result of a calculation to a text message.
Now, double-click or right-click on the output shape to edit it.

Step6

A window will appear titled "Output Properties". Using this window, you can specify what will be displayed on 
the screen. Output shapes are fairly simple. They will output the result of an expression. This can be something
like a text message, a variable, or the result of a calculation. In the box, type "Hello, world!". You have to add 
the double-quotes around the text. In computer programming, this is called a String. Now, click on OK to
continue. You might get an error window if you didn't type it in correctly. If that happens, just edit the shape
again and fix it.


Step7


The Output shape will now appear in green.
Since all the shapes are in color (nothing is gray), your program is complete. Now it is time to run it.
On the main toolbar, you should see a green icon that looks like the Play Button you use when playing a DVD 
or watching a video on YouTube. Click on this icon to run your program. You can also press F5 on your 
keyboard or select Run from the Program menu.



Step8

A new window should appear called the "Console Screen". In computer programming, the console is used to
display and input textual information. The Console Screen in Flowgorithm was modeled after the texting 
windows you use on your phone. So, it is like you are texting Flowgorithm!

Anyway, you have finished your first computer program. Congratulations!
