Flowchart

When a program starts to get long and complicated, programmers use flowcharts to divide the program into sections.

We will use Dia to draw the flowchart on the computer.

• Open dia from the menu or the command line.
• Click `file->New diagram'
• Pick `Flowchart' from the drop down box in the middle of the Diagram Editor toolbox.
• Each action that the computer will do goes in a text box
• Each Control Structure (in this case `if') goes in a text diamond
• Each action that the player at the keyboard will do goes in an ellipse

The arrows between the boxes, diamonds and ellipses show the flow of the program.
